An Insight to Small Business Professor Ramos Blog

An Insight to Small Business Small businesses are corporations, partnerships, and sole proprietorships that have less employees along with revenue because they are not the same size as a â€Å"regular† corporation that operates on a larger scale. Small businesses offer services such as convenient stores, small grocery stores, restaurants, bakeries, hairdressers, tradespeople such as carpenters and electricians, photographers, and some small-scale manufacturing such as toy manufacturing, being a smart phone accessory maker, or a plastic container manufacturer. Most small businesses are sole-proprietor operations meaning they provide low income for doing things like selling prepared hot food on the street. Small businesses can range from fifteen employees to no more than five thousand. According to Jason Nazar’s contributed statistics in Forbes, there are almost 28 million small businesses in the United States, with approximately 543,000 of these new businesses starting up each month. United States small businesses employee nearly 60 million people, which is nearly 40 percent of the private workforce, and they have generated over 65 percent of new jobs since 1995. Firms with fewer than one hundred employees actually hold a wide variety of the over all small business employment (see Figure 1 for the ratio between firm size to employment).   https://www.sba.gov/sites/default/files/March_April_2016_FINAL_508_compliant.pdf Aside from the small businesses that maintain full-time or part-time employees, there are businesses that employ nobody other than the owner themselves. A nonemployer business is one that has no paid employees, annual business receipts of $1,000 or more and must pay federal income taxes. Most nonemployers are self-employed individuals operating very small unincorporated businesses, depending on the owners source of capital (money). Nazar states that around 75 percent of all United States businesses are nonemployer businesses and that around 80 percent of these non-employee businesses reported less than $50,000 in receipts which is considered low income even though over 22 million are self-employed and can take in all revenue made. These statistics show that it can be extremely challenging to invest into your own small business venture, but sometimes the ambition does prove to pay off in the long run. Even though starting up your own small business may require a lot out of you physically and mentally, the financial cost of starting up is not as large as Americans make it out to be. The annual cost of starting up a small business can be as low as $3,000, however most home-based franchises cost $2,000 to $5,000 to start. If you’re someone who is interested in a career focused on web design or computer programming then you can even start your small business online, which can be most beneficial for networking connections through social media or running a website. According to eMarketer, an online digital marketer, there was a 24.8 percent increase in the annual Online Small Businesses, the global worldwide sales reached $2.304 trillion and online businesses accounted for 58.9 percent of those sales (Pilon). As online business continues to be a larger factor of the retail market around the world, getting your business ideas online can be a convenient way to network with people a round you and if you’re lucky all that you really need to get your business started is that first good connection. Online businesses are growing at double digit rates and you need to be able to capture the public’s attention and expose your latest online business ideas to encourage growth within your own business. If you have started a small business then I’m sure you have struggled with some sort of lack in cash flow which is a very common difficulty that business owners experience. In 2014,   220,000 establishments (small businesses) started in the United States and 205,000 exited the United States due to not having enough revenue (Nazar). Every business has its own financing needs; experts have some tips to help you figure out how much cash you will actually need to start your own small business. Entrepreneur Drew Gerber, who started a technology company, a publicity firm and a financial planning company, estimates that an entrepreneur will need six months’ worth of fixed costs just to start their own small business. Gerber instructs, â€Å"Have a plan to cover your expenses in the first month, Identify your customers before you open the door so you can have a way to start covering those expenses†. One of the main reasons most small businesses fail is that they simply run out of cash. Writing a business plan without basing your forecasts on reality often leads to an unfortunate, and often unnecessary, business failure. Without the benefit of experience or actual historical financials, it’s easy to overestimate a new company’s revenue and underestimate costs (McCahon). Twenty percent of small businesses fail in their first year, thirty percent of small businesses fail in their second year and fifty percent of small businesses fail after five years. Finally, thirty percent of all small businesses fail in their tenth year in business (Georgia McIntyre). There are many reasons why small businesses fail but a few things that tend to do harm are: Capital access (access to money), cash flow, lack of demand, and poor management. One of the major problems with small businesses is capital, as of 2015, seventy-three percent of small business owners weren’t able to access enough capital for their business ( https://www.fundera.com/blog/what-percentage-of-small-businesses-fail). This means that even if the money existed in a business account, a business owner cannot access it when needed for business operations, making it extremely challenging to run your business efficiently. California governmental agencies, small business organizations and state legislators come together every year to recognize that owning and starting your business is hard work. This annual event honors a few of the millions of small business that serve as â€Å"the economic engine of California†. Small businesses are engrained in California’s communities and economy contributing to 75 percent of California’s gross state product and over half of the states private sector jobs. â€Å"California Small Business Day† also allows business owners from across the state to connect with other business owners in an effort to learn from or gain insight from fellow entrepreneurs. According to a small-town and successful business owner, John Hackney, â€Å"This business can either make or break you, you have to be willing to sacrifice everything you have in order to start your own business.† He claims that the initial starting phase of your business will be one of the hardest periods of growth that you have to overcome through the entire process. Hackney also advises that if you plan your costs, don’t underestimate the expenses, and never forget that they can rise as the business grows, it’s easy to overlook costs when you’re thinking about the big picture, but you should always be very precise and thorough when planning for your fixed expenses. He also strongly believes that when your employees are appreciated and treated with respect, then you are sure to succeed in maintaining a loyal, hardworking staff. Ideals like these reveal why small businesses are so important and even endearing. We can come to the conclusion that even though starting your own business may seem to be one of the hardest things, it can also be equally as rewarding and beneficial.    California Small Business Association, â€Å"California Small Business Day 2018†, Business Wire (English). 06/19/2018, Article Retrieved from http://search.ebscohost.com/login.aspx?direct=truedb=bwhAN=bizwire.c85292394site=ehost-live Richard Schwinn: PhD, Research Economist, â€Å"2016 State Small Business Profiles Released with Fresh Design†, The Small Business Advocate: Office of Advocacy, Vol. 35, No. 3, March- April 2016 Retrieved from https://www.sba.gov/sites/default/files/March_April_2016_FINAL_508_compliant.pdf Jason Nazar, â€Å"16 Surprising Statistics About Small Businesses†, Small Business Administration Office of Advocacy, Sep 9, 2013 Retrieved from https://www.forbes.com/sites/jasonnazar/2013/09/09/16-surprising-statistics-about-small-businesses/#269ebc195ec8 â€Å"Small Business†, page issues Retrieved from https://en.m.wikipedia.org/wiki/Small_business Georgia McIntyre, â€Å"What is the Small Business Failure Rate?†, What Percentage of Small Businesses Fail?

Cross-Cultural Communication Essay Example | Topics and Well Written Essays - 1000 words

Cross-Cultural Communication - Essay Example In today’s world of cultural diversity, emotions like empathy can really help more than sympathy in improving cross-cultural communication between the native people and foreigners in any place. Bennette (11) says that the communication strategy which is most suitable in context of cultural diversity, is empathy which literally helps people from diverse backgrounds understand and respect each other’s feelings and values. It is suggested that empathy works more magic than sympathy in ensuring successful cross-cultural communication because this makes an individual actually participate in others’ sorrows, rather than merely imagining him/herself in the depressed person’s position. This sort of an empathic attitude really helps in incorporating the necessary element of understanding in cross-cultural communication. Cultural empathy phenomenally aids in communication because in this way, one really seeks to learn and comprehend what viewpoints other person†™s culture presents about myriad issues, and this results in a very strong connection between two culturally diverse people. In a story â€Å"A Town Called Rosewood† written by (Carnes, Tauss, and Blackmun), it is mentioned how race and other such stereotypes mattered greatly in the destruction of a whole town called Rosewood and how its population got homeless and scattered as a result of the horrendous massacre initiated by the biased white people back in 1923. the uncontrollable mess all started when a black man falsely accused and this gave the white neighbors an unjustified chance to crackdown on the town mostly occupied by the less influential black people. Following are two letters addressed to each of the two groups, the native residents of Rosewood and their more influential white neighbors in an effort to inform each party about the values and cultural norms

International Marketing - Term Paper Example This report provides a macro analysis of China, one of the fastest growing markets in the world and which provides a suitable platform for a business to invest. One of the many admirable factors about China is its political stability. This gives businesses the confidence of establishing and expanding their businesses as they are assured of enhanced security. China is a single party state which is governed and controlled by the Communist Party. The single party aspect reduces the chances of political wrangles and further reduces the chances of politicians interfering with the business operations (Hale and Long, 80). Though the tariffs in China are high, they have been drastically reducing over the past few years. However, the government still has a lot to do when dealing with e-commerce businesses. The legal framework adopted for e-commerce insufficiently addresses intellectual property, and consumer rights are yet to be satisfactorily addressed (Hartman and Brown, 2013). Even with the few challenges, the political environment in China provides a healthy platform for businesses to operate. The economic environment is the second most important factor (after political) in determining whether a business shall succeed in a country. China’s economic environment has continued to be favourable to businesses, especially with the increasing demand. Based on nominal GDP and the purchasing power parity, China is ranked second, with the first position being America (InvestinChina, 2014). It has constantly experienced an increase and growth in GDP by about 7 %, and it’s GDP, by 2013 stood at 9.82% (Shao and Gui, 2014). This depicts the promising market in China, and businesses that invest here have high chances of succeeding. In addition, the inflation in China is lower as compared to many other developed countries, having a 2.5% inflation rate (InvestinChina, 2014) and an unemployment rate of 4.1%. The growth in GDP is as depicted in the diagram

How Does Poverty Cause Crime Criminology Essay

How Does Poverty Cause Crime Criminology Essay In the current essay we will discuss the fact that poverty causes crime. Poverty is a characteristic of the economic situation of the individual or social group in which they cannot satisfy a certain range of the minimum requirements needed for life saving ability.   Poverty is a relative concept and depends on the overall standard of living in this society. According to experts, not getting decent wages for their work, young people gradually lose the desire to marry, marry, have children they are full of fear for tomorrow, not sure that tomorrow they will not be fired because of another financial crisis. In addition, low wages and lack of jobs, experts say, are pushing young people to commit crimes in order to get rich quickly.   It is, therefore, among criminals, increases the number of adolescents, aged 18 to 25 years. Poverty is a consequence of diverse and interrelated reasons, which combine into the following groups: economic (unemployment, low wages, low productivity, lack of competitiveness of the industry); socio-medical (disability, old age, high levels of morbidity); Demographic (parent families, a large number of dependents in the family); socio-economic (low level of social guarantees); educational qualifications (a low level of education, lack of training); political (military conflict, forced migration); regional-geographic (uneven development of regions). As well, current crisis makes people react and do something, even if it is illegal, they start committing a crime. Poverty causes many crimes, as if a person was not poor and had faith in himself, he would not face the thought that he should search another ways to get money. Being poor, which could be caused by different reasons, makes a person unhappy, incapable to earn enough money, to buy anything he wants or at least something necessary. Poverty determines a certain stereotype in a persons thoughts, and he does not see any constructive solving of the problem, as he wants to choose the easiest way of getting money, even harming other people. Poverty has a huge psychological influence on people, who become depressed, desperate and then they decide to commit a crime, as they have not found anything that can legally get them out of such situation. Too many problems that a person faces in the modern society makes him get angrier on the whole situation and look for the new way of solving their problem. The desperate economical situation in the country and consequently the lack of the work places especially for young people creates the thoughts and actions of crime. No guarantees from the government and no proper help to people who are poor, leads to the chaos and misunderstanding, where the only way out they find is to commit a crime. Poverty as a social phenomenon in a historical sense is of lasting value.   The extent and depth of immersion of the people in the country reflects two important aspects of society the level of development of productive forces and the corresponding character of their operation principle of social justice. Most often, poverty is treated as financial insecurity of people, when income of a person or family does not allow maintaining socially necessary consumption for life, interfering with normal living and personal development. Poverty serves as guidelines for shaping social policy.   This phenomenon is assessed by using indicators of absolute and relative poverty, its depth and severity, as well as by the subjective perception of their individual well-being and quality of life. To determine the effect of poverty on crime, there may be also another way: by studying the living conditions of the poor and convicted before they commit crimes. As a consequence of the fact that poverty causes crime, criminally distorted psychology of society, values, personality as a direct cause of crime are expressed by more than just greed, aggression, irresponsibility and neglect of criminal law prohibitions.   It has several forms: greed, greed, the cause component of the Organized Crime and Entrepreneurship, greed, parasitism, generating professional and recidivism, greed, irresponsibility, have a drunken crime, situational robbery and looting teens, when crimes are committed to meet the immediate material needs  , greed, poverty, which is based on physical survival.   At a gain now there is 80% of the totality of the causes of crime at this time. The main source of crime in any society is the aggravation of his social contradictions. It is also defined as meaningful and quantifiable features of the formation are within a specific time parameters.   It is known that the technologically advanced capitalist countries do not have the same crimes. As a fact, crimes begin from the childhood. As a rule, if a child was born in a poor family, there are more chances that he will start committing crimes. All over the world there is propaganda of a luxurious way of life, of successful people, of expensive mansions, cars, of beautiful journeys, etc. When children and adolescents see that and understand that parents will not provide them with all these things, they start looking for the opportunity to get money fast to buy at least something. And consequently they decide to commit a crime. The crimes committed by adolescents are considered the cruelest. The majority of cases of all crimes show that a driving force of the crimes is the money. The values of the society are built the way that those people with the problems in their minds decide to bring closer all these luxurious things. One of the main aspects that can prevent poverty is education. If children are educated properly, then they will perceive the reality as it is and they will try to succeed in legal ways to study, to get a job. Sometimes, crimes are the symptom of the culture, and education can cure the cultural poverty and financial poverty will be cured itself, as a consequence. As a fact, not only poor people commit crimes, as there are also rich people who have no boundaries in their actions and power and they also commit crimes to get more money and power. Considering the statistics, the total number of the seven index crimes is reported to police per 100,000 inhabitants in the United States. The research states that if to reduce poverty, crime will be reduced, although with the crisis that has begun in 2008, there have been registered less crimes, although there are more poor people because of the crisis. As an example of it, in the first decade of the XXI century crime in the United States has tended to decline. By the end of the decade, crime rates, according to many indicators, have fallen dramatically, despite the economic crisis of 2008-2010.   In some cities such as New York, the crime rate has dropped to the record lows. With the onset of recession in the U.S., many media outlets have expressed fears that the crisis (for example, increased unemp loyment and reduced real incomes of people) will lead to a rapid increase in crime.   FBI report shows that these fears have not yet met.   Published in the 2008, the study of the Heritage Foundation showed that the relationship between economic perturbations and crime exists, but it is not so clear.   Thus, in the United States there is a nation-wide crime statistics since 1934.   During all this time only for 16 years the crime rate has declined.   The crime rate has steadily increased from 1955 to 1972, although this time the U.S. economy has experienced a rapid period of development, weak, a recession occurs only in mid-1960.   In turn, during the Great Depression statistics was only for the period from 1934 to 1938 criminals showed less activity.   Federal Bureau of Investigation (FBI) issued a preliminary report on crime rates in the U.S. in 2009.   This statistics is based on data provided by about 17 thousand law enforcement agencies of different jurisdictions.   The main conclusions of the report compared to 2008, the number of property crimes in the U.S. decreased by 6.1%, violent crimes by 4,4%.   According to the report, this year the number of murders in the U.S. fell by 10%, robberies on 6,5%, rape by 3,3%.   Among property crimes, the most significantly decreased the number of thefts of cars (by 18,7%), theft (by 5,3%) and burglary (2.5%).   The greatest reductions in crime noted in cities with populations exceeding one million. In addition to FBI statistics, the crime rate measures the U.S. Bureau of Justice Statistics by the Census Bureau (study called National Crime Victimization Survey). Since 1973, there have been annually polled 70-80 thousand of households (family or group of people living togethe r and having a total budget), to identify about how many actually committed crimes Americans have not informed the police.   The last time similar research was conducted in 2008.   It showed that the victims of the criminals, Americans turn to law enforcement agencies do not always: becoming the victims of violent crimes, they shall notify the police in 51,2% of the property in 39,6% of cases. Another important indicator for gauging the level of crime in the U.S. is a traditional study conducted the service Gallup Rating the perception of crime.   Every year Gallup asks Americans to estimate increased or decreased the number of crimes in their area and across the country.   In the recent years, such survey was conducted in September 2009.   Then 74% of Americans said that compared with last year the crime rate in the U.S. grew on 15% reported that the situation has improved.   The rise in crime in their area was 51% decrease 29%.   As a fact, 12% of respondents said that the situation with crime in their place of residence was very serious; the crime rate across the United States similarly estimated 55% of respondents.   It is curious that in the last decade, both of these indicators remain fairly stable, fluctuating slightly. As a rule, those countries where there is no proper economic regulations, there are more chances that people will react negatively and commit more crimes, as the consequence of unhappy life and no perspective in such countries. Although there is no proof of the direct connection of the fact that poverty is the main motive to commit a crime, as there are many factors present in the minds of people who in different situations can act differently. It is not quite explicable that fact that while there is a depression and economical crisis all over the world, people do not commit more crimes, as the statistics shows that people do not intend to commit more crimes. The consequences and the logic of this fact are not fully understandable. In the modern world everything changes so quickly that people get accustomed to the situation, they learn the rules of the game and probably they try to find a better way to earn money and succeed than to commit a crime. There can be also hope that the mor e people get more education, the more they get knowledge, the better they understand life and the rules to survive. The more people know, the better they understand the situations, the values, the perspective, the more ideas they have, the more creative they are and the more they feel capable to find a job and to succeed in life. In poor countries such as Brazil and the countries of the former Soviet Union, there are millions of poor people who do not have a way out because of the lack of any perspectives to find a job, as the level of corruption is extremely high. In such countries it is especially visible the difference and the gap between the extremely rich and very poor people. There are almost no middle class people who have a job, a house and other benefits. That is why there are almost no chances to combat it, as poor and desperate people in these countries do not see any other opportunity except committing a crime. The obvious injustice and no social guarantees make people feel as losers, who see the luxurious life and who cannot touch it. As a fact, there is a lot of envy because of such a big gap and so much poverty. Each country has its problems and level of poverty, but there is one main point- the lack of money. If people had money at least for the basic needs, there would not be such level of poverty. And as Aristotle said: Poverty a source of disturbance and crime, which means that little problem becomes a huge problem if there is nothing useful done to prevent it. That is why the right policy of the country will be able to eliminate poverty and along with that there will be no crime in the future. What factors specifically lead to poverty in the countries?   This high level of unemployment, a significant number of jobs that do not provide a living wage, as well as reducing the number of social service costs. It can be emphasized that poverty reduction should not be a charity event.   It must go against strong social inequalities.  The only way to do this is to foster a society of equal opportunities. If we deal only with short-term problems in order to achieve short term objectives rather than to focus on strategic issues of economic and social development, we may miss the last chance to make the country the basis for a viable, long-term development based on economic and social modernization. So, the agenda should include the following vital issues: Reducing inequality and providing our citizens the opportunity to realize their constitutional rights; Restoration of a common economic space; Infrastructure development through the joint efforts of government and the private sector (roads, railways, ports, airports, bridges, power lines, electricity, etc.); The solution of demographic problems of the countries; The rise of living standards (including environmental problems); Eliminating unevenness in the level of regional development; Harmonization of interethnic relations in the country and the creation of normal living conditions for the communities living outside of Russia; National security and territorial integrity; The safety of citizens; As a fact, it is easier to prevent poverty than to deal with its consequences. The fact that people commit crimes when they are poor does not justify them. But the government has to take measures to prevent the poverty, there should be created more opportunities for people to work, as keeping people busy can prevent crimes and even the thoughts of it. Proper economical policy, positive changes in the social sphere, economical issues and employment can guarantee the higher level of education and understanding the principles, which will avoid the crime in the future. There should be also organized the certain campaigns aimed at the reduction of poverty, as it in some cases causes crime. Anyway, if the importance of money wan not so crucial these days, probable the majority of people would not commit crimes. As it is very difficult to be different from everyone in the society that value the materialistic ideas, the goods and products, it becomes a real challenge not to have goals to buy, to own something. It happens because the society judges those who are different, who has different vision, goals, principles and ideas. That is why people are almost forced to do everything the right way to be as everyone else is, to work and to succeed. And if there are no possibilities for that in the country, people start looking for other, wrong ways to reach it anyway. They start looking for the easiest, quickest and lowest ways to reach their goal, and that is why robberies, different violent crimes and thefts occur. Some people after committing them feel innocent, as they think that if the government did not give certain things and possibilities to them, then they have the rig ht to take things or money from the richer people. Deceiving themselves, people live in their own world that is so narrow, that allows them to commit a crime and to presume that no one will ever know. As a fact, it is sad that a reality is that money takes a very important place in peoples lives. Everything people do to earn money sometimes in not enough, that is why arise different problems which lead to the thoughts to commit a crime as that last opportunity. Everyone wants to live worthily and this desire determines unexpected behavior. Often people want to prove something to their friends, family, loved ones, but they do not manage to achieve it in a legal way, choosing instead the lowest possible way to commit a crime, thinking that from that moment on everything would change for the better. It is obvious that money rules the world, which is why almost every crime is based on the desire to get more money at any cost. Those who commit crime do not usually think about consequences and they pay for everything they have done later. Sometimes people just lack the patience and they want to have everything too soon without any considerable long time efforts. Consequently, this practice does not work and people are forced to pay for everything they have done. Psychological help and support in difficult situations can help and benefit people to overcome difficulties, challenging times and other problems. Being open to discussions, to new ideas, to new opportunities and options, people can stop thinking about committing a crime because they are poor. The capacity to believe in yourself, in the future possibilities and in the brighter future lacks in the minds of the people. It is surprising that people commit crimes, as it is obvious that sooner or later they will pay for what the y have done and it is important to take control of the life. The mistake is that people sometimes consider themselves cleverer than the others and think they are capable of changing they life easily by harming someone else. This method, fortunately, does not work. Being realistic and optimistic at the same time can save situation and turn life to the better. All in all, only the right policies of the countries can solve this problem and make people understand and see other right ways to earn money and to get out of poverty. People are instruments in the hands of the government and they play by its rules. If there will be more opportunities and proper social conditions for people to live and work, the crimes that are caused by poverty will not take place anymore. A lot depends on the country people live in and on the fact how they see their future, which possibilities and advantages they see and want to implement in their life. Anyway, everything depends on a choice a person makes, wherever he lives and whatever he has.

RESULS & CONCLUSION31 7. REFERENCES32 APPENDIX 1. INTRODUCTION With a unique array of configurable digital and analog blocks, the Programmable System-on-Chip is a true systemlevel solution, offering a modern method of signal acquisition, processing, and control with exceptional accuracy, high bandwidth, and superior flexibility. Its analog capability spans the range from thermocouples (DC voltages) to ultrasonic signals. PSoC 5 (CY8C55xxx, CY8C54xxx, CY8C53xxx, CY8C52xxx) families are fully scalable 8-bit and 32-bit PSoC platform devices that share these characteristics:  ¦ Fully pin, peripheral compatible  ¦ Same integrated development environment software  ¦ High performance, configurable digital system that supports a wide range of communication interfaces, such as USB, I2C, and CAN  ¦ High precision, high performance analog system with up to 20-bit ADC, DACs, comparators, opamps, and programmable blocks to create PGAs, TIAs, mixers, etc.  ¦ Easily configurable logic array  ¦ Flexible routing to all pins  ¦ High performance, 8-bit single-cycle 8051 (PSoC 3) or 32-bit ARM Cortex-M3 (PSoC 5) core . 1 OBJECTIVE * 8051 or Cortex-M3 Central Processing Unit (CPU) with a nested vectored interrupt controller and a high performance DMA controller * Several types of memory elements including SRAM, flash, and EEPROM * System integration features, such as clocking, a featurerich power system, and versatile programmable inputs and outpu ts 2. TOP LEVEL ARCHITECTURE 2. 1 CPU SYSTEM 2. 1. 1 PROCESSOR The PSoC 5 CPU subsystem is built around a 32-bit three stage pipelined ARM Cortex-M3 processor running up to 80 MHz. The PSoC 5 instruction set is the same as the Thumb-2 instruction set available on standard Cortex- M3 devices. Three stage pipelining operating at 1. 25 DMIPS/MHz. This helps to increase execution speed or reduce power. * Supports Thumb-2 instruction set: * The Thumb-2 instruction set supports complex operations with both 16- and 32-bit instructions * Atomic bit level read and write instructions * Support for unaligned memory access * Improved code density, ensuring efficient use of memory. * Easy to use, ease of programmability and debugging: * Ensures easier migration from 8- and 16-bit processors * Nested Vectored Interrupt Controller (NVIC) unit to support interrupts and exceptions: * Helps to achieve rapid interrupt response Extensive debug support including: * Serial Wire Debug Port (SWD-DP), Serial Wire JTAG Debug Port (SWJ-DP) ? Break points ? Flash patch ? Instruction tracing ? Code tracing 2. 1. 2 INTERRUPT CONTROLLER The CPU subsystem includes a programmable Nested Vectored Interrupt Controller (NVIC), DMA (Direct Memory Access) controller, Flash cache ECC, and RAM. The NVIC of bot h PSoC 3 and PSoC 5 devices provides low latency by allowing the CPU to vector directly to the first address of the interrupt service routine, bypassing the jump instruction required by other architectures. The PSoC 5 interrupt controller also offers a few advanced nterrupt management capabilities, such as interrupt tail chaining to improve stack management with multiple pending interrupts providing lower latency. Supports 32 interrupt lines * Programmable interrupt vector * Configurable priority levels from 0 to 7 * Support for dynamic change of priority levels * Support for individual enable/ disable of each interrupt * Nesting of interrupts * Multiple sources for each interrupt line (can be either fixed function, UDB, or from DMA) * Supports both level trigger and pulse trigger * Tail chaining, late arrivals and exceptions are supported in PSoC ® 5 devices 2. 1. DMA CONTROLLER The DMA controller allows peripherals to exchange data without CPU involvement. This allows the CPU to run slower, save power, or use its cycles to improve the performance of firmware algorithms. * Uses the PHUB for data transfer * Includes 24 DMA channels * Includes 128 transaction descriptors (TD) * Eight levels of priority per channel * Transactions can be stalled or canceled * Each transaction can be from 1 to 64 KB * Large transactions can be broken into smaller bursts of 1 to 127 bytes. * Each channel can be configured to generate an interrupt at the end of transfer 2. 1. 4 CACHE CONTROLLER In PSoC 5 devices, the flash cache also reduces system power consumption by reducing the frequency with which flash is accessed. The processor speed itself is configurable allowing for active power consumption tuned for specific applications. * Instruction cache * Direct mapped * 128 bytes total cache memory * Registers for measuring cache hit/miss ratios * Error correction code (ECC) support * Error logging and interrupt generation * Designed to put flash into sleep automatically to save power 2. 2 MEMORY The PSoC nonvolatile subsystem consists of Flash, bytewritable EEPROM, and nonvolatile configuration options. The CPU can reprogram individual blocks of Flash, enabling boot loaders. An Error Correcting Code (ECC) can enable high reliability applications. A powerful and flexible protection model allows the user to selectively lock blocks of memory for read and write protection, securing sensitive information. The byte-writable EEPROM is available on-chip for the storage of application data. Additionally, selected configuration options, such as boot speed and pin drive mode, are stored in nonvolatile memory, allowing settings to become active immediately after power on reset (POR). 2. 2. 3 NON VOLATILE LATCH A Nonvolatile Latch (NVL or NV latch) is an array of programmable, nonvolatile memory elements whose outputs are stable at low voltage. It is used to configure the device at Power on Reset. Each bit in the array consists of a volatile latch paired with a nonvolatile cell. On POR release nonvolatile cell outputs are loaded to volatile latches and the volatile latch drives the output of the NVL. FEATURES * A 4Ãâ€"8-bit NV latch for device configuration * A 4Ãâ€"8-bit Write Once NV latch for device security 2. 2. 4 SRAM PSoC ® 3 and PSoC ® 5 devices include on-chip SRAM. These families offer devices that range from 2 to 64 kilobytes. PSoC 3 devices offer an additional 4 kilobytes as a trace buffer. * Organized as up to three blocks of 4 KB each, including the 4 KB trace buffer, for CY8C38 family. * Organized as up to 16 blocks of 4 KB each, for CY8C55 family. * Code can be executed out of portions of SRAM, for CY8C55 family. * 8-, 16-, or 32-bit accesses. In PSoC 3 devices the CPU has 8-bit direct access to SRAM. * Zero wait state accesses. * Arbitration of SRAM accesses by the CPU and the DMA controller. * Different blocks can be accessed simultaneously by the CPU and the DMA controller. 2. 2. 5 FLASH PROGAMMING MEMORY PSoC 3 and PSoC 5 include on-chip Flash memory. These two families offer devices that range from 16 to 256 kilobytes. Additional Flash is available for either error correction bytes or data storage. PSoC 3 and PSoC 5 Flash memory have the following features: * Organized in rows, where each row contains 256 data bytes plus 32 bytes for either error correcting codes (ECC) or data storage. * For PSoC 3 architecture: CY8C38 Family, organized as one block of 64, 128, or 256 rows. * For PSoC 5 architecture: CY8C55 Family, organized as either one block of 128 or 256 rows, or as multiple blocks of 256 rows each. Stores CPU program and bulk or nonvolatile data * For PSoC 5 architecture: CY8C55 Family, 8-, 16-, or 32-bit read accesses. PSoC 3 architecture has only 8-bit direct access. 2. 2. 6 EEPROM PSoC 3 and PSoC ®5 devices have on-chip EEPROM memory. These two families offer devices that range from 512 bytes to 2 kilobytes. * PSoC 3 and PSoC 5 EEPROM memory have the following features: * Organized in rows, where each row contains 16 bytes * Organized as one block of 32, 64, or 128 rows, depending on the device * Stores nonvolatile data * Write and erase using SPC commands Byte read access by CPU or DMA using the PHUB * Programmable with a simple command/status register interface EEPROM memory provides nonvolatile storage for user data. EEPROM write and erase operation is done using SPC commands. It may be read by both the CPU and the DMA controller, using the PHUB. All read accesses are 8-bit. 2. 2. 7 EMIF PSoC 3 and PSoC 5 architectures provide an external memory interface (EMIF) for connecting to external memory devices and peripheral devices. The connection allows read and write access to the devices. The EMIF operates in conjunction withUDBs, I/O ports, and other PSoC 3 and PSoC 5 components to generate the necessary address, data, and control signals. The EMIF does not intercept address data between the PHUB and the I/O ports. It only generates the required control signals to latch the address and data at the ports. The EMIF generates a clock to run external synchronous and asynchronous memories. It can generate four different clock frequencies, which are the bus clock divided by 1, 2, 3, or 4. The EMIF supports four types of external memory: synchronous SRAM, asynchronous SRAM, cellular RAM/PSRAM, and NOR Flash. External memory can be accessed via the 8051 xdata space or the ARM Cortex-M3 external RAM space; up to 24 address bits can be used. The memory can be 8 or 16 bits wide. 2. 3 SYSTEM WIDE RESOURCES 2. 3. 1 CLOCKING SYSTEM The clock system has these: * Four internal clock sources increase system integration: * 3 to 67 MHz Internal Main Oscillator (IMO)  ±1% at 3 MHz * 1 kHz, 33 kHz, 100 kHz Internal Low Speed Oscillator (ILO) outputs * 12 to 67 MHz clock doubler output, sourced from IMO, MHz External Crystal Oscillator (MHzECO), and Digital System * Interconnect (DSI) 24 to 67 MHz fractional Phase-Locked Loop (PLL) sourced from IMO, MHzECO, and DSI * DSI signal from an external I/O pin or other logic as well as a clock source * Two external clock sources provide high precision clocks: * 4 to 33 MHz External Crystal Oscillator (MHzECO) * 32. 768 kHz External Crystal Oscillator (kHzECO) for Real Time Clock (RTC) * Dedicated 16-bit divider for bus clock Eight individually sourced 16-bit clock dividers for the digital system peripherals * Four individually sourced 16-bit clock dividers for the analog system peripherals * IMO has a USB mode that auto locks to the USB bus clock, requiring no external crystal for USB. (USB equipped parts only) 2. 3. 2 POWER SUPPLY AND MONITORING PSoC 3 and PSoC 5 devices have separate external analog and digital supply pins, labeled respectively Vdda and Vddd. The devices have two internal 1. 8V regulators that provide the digital (Vccd) and analog (Vcca) supplies for the internal core logic. The output pins of the regulators (Vccd and Vcca) have very specific capacitor requirements that are listed in the datasheet. These regulators are available: * Analog regulator for the analog domain supply * Digital regulator for the digital domain supply * Sleep regulator for the sleep domain * I2C regulator for powering the I2C logic * Hibernate regulator for supplying keep alive power for state retention during hibernate 2. 3. 3 WATCH DOG TIMER The Watchdog Timer (WDT) circuit automatically reboots the system in the event of an unexpected execution path. This timer must be serviced periodically. If not, the CPU resets after a specified period of time. Once the WDT is enabled it cannot be disabled except during a reset event. This is done to prevent any errant code from disabling the WDT reset function. To use the WDT function, the user is required to enable the WDT function during their startup code. The WDT has the following features: * Protection settings to prevent accidental corruption of the WDT * Optionally-protected servicing (feeding) of the WDT * A configurable low power mode to reduce servicing requirements during sleep mode * A status bit for the watchdog event that shows the status even after a watchdog reset 2. . 4RESET POWER ON RESET Power on Reset (POR) is provided primarily for a system reset at power up. The IPOR will hold the device in reset until all four voltages; Vdda, Vcca, Vddd, Vccd, are to datasheet specification. The POR activates automatically at power up and consists of: An imprecise POR (IPOR) – is used to keep the device in reset during i nitial power up of the device until the POR can be activated A precision POR (PRES) – derived from a circuit calibrated for a very accurate location of the POR trip point. The power on RESET clears all the reset status registers WATCHDOG RESET Watchdog Reset (WRES) detects errant code by causing a reset if the watchdog timer is not cleared within the userspecified time limit. The user must always set the WRES initialization code. This was done to allow the user to dynamically choose whether or not to enable the watchdog timer SOFTWARE INITIATED RESET Software Initiated Reset (SRES) is a mechanism that allows a software-driven reset. The RESET_CR2 register forces a device reset when a 1 is written into bit 0. This setting can be made by firmware or with a DMA. The RESET_SR0 [5] status bit becomes set on the occurrence f a software reset. This bit remains set until cleared by the user or until a POR reset. EXTERNAL RESET External Reset (XRES_N) is a user-supplied reset that causes immediate system reset when asserted. XRES_N is available on a dedicated pin on some devices, as well as a shared GPIO pin P1[2] on all devices. The shared pin is available through a customer-programmed NV Latch setting and supports low pin count p arts that don't have a dedicated XRES_N pin. This path is typically configured during the boot phase immediately after power up. 3. CONCLUSION
