The Evolution Of The Microprocessor (2131 words) Essay Example For Students

The Evolution Of The Microprocessor (2131 words) Essay The Evolution Of The MicroprocessorTheEvolution Of The MicroprocessorOnly once in a lifetime will a new inventioncome about to touch every aspectof our lives. Such a device thatchanges the way we work, live, and play is a specialone, indeed. The Microprocessorhas been around since 1971 years, but in the last fewyears it has changed the American calculatorsto video games and computers (Givone1). Many microprocessors have beenmanufactured for all sorts of products; somehave succeeded and some have not. This paper will discuss the evolution and historyof the most prominent 16 and 32 bit microprocessorsin the microcomputer and howthey are similar to and different fromeach other. Because microprocessors are a subject thatmost people cannot relate to and donot know much about, this paragraph willintroduce some of the terms that will be in-volved in the subsequent paragraphs. Throughout the paper the 16-bit and 32-bit mi-croprocessors are compared and contrasted. The number 16 in the 16-bit microproces-sor refers how many registers there areor how much storage is available for the mi-croprocessor (Aumiaux, 3). The microprocessorhas a memory address such as A16,and at this address the specific commandsto the microprocessor are stored in thememory of the computer (Aumiaux, 3). So with the 16-bit microprocessor there are576 places to store data. With the32-bit microprocessor there are twice as manyplaces to store data making the microprocessorfaster. Another common term which is mentionedfrequently in the paper is the oscil-lator or the time at which the processorsclock ticks. The oscillator is the pacemaker for the microprocessor which tellswhat frequency the microprocessor can proc-ess information, this value is measuredin Mega-hertz or MHz. A nanosecond is ameasurement of time in a processor, ora billionth of a second. This is used to measurethe time it takes for the computer toexecute an instructions, other wise knows as a cy-cle. There are many different types ofcompanies of which all have their own familyof processors. Since the individualprocessors in the families were developed over afairly long period of time, it is hardto distinguish which processors were introduced inorder. This paper will mention thefamilies of processors in no particular order. Thefirst microprocessor that will be discussedis the family of microprocessors called the9900 series manufactured by Texas Instrumentsduring the mid-70s and was developedfrom the architecture of the 900 minicomputerseries (Titus, 178). There were five dif-ferent actual microprocessors that weredesigned in this family, they were theTMS9900, TMS9980A, TMS9981, TMS9985, andthe TMS9940. The TMS9900 wasthe first of these microprocessors sothe next four of the microprocessors where simplyvariations of the TMS9900 (Titus,178). The 9900 series microprocessors runs with64K memory and besides the fact that the9900 is a 16-bit microprocessor, only 15 ofthe address memory circuits are in use(Titus, 179). The 16th address is used for thecomputer to distinguish between word anddata functions (Titus, 179. The 9900 seriesmicroprocessors runs from 300 nanosecondsto 500 ns from 2MHz to 3.3MHz andeven some variations of the original microprocessorwhere made to go up to 4MHz(Avtar, 115). The next microprocessor that willbe discussed is the LSI-11 which was pro-duced from the structural plans of thePDP-11 minicomputer family. There are threemicroprocessors in the LSI-11 family theyare the LSI-11, LSI-11/2, and the much im-proved over the others is the LSI-11/32(Titus, 131). The big difference between theLSI-11 family of microprocessors and othersimilar microprocessors of its kind is theyhave the instruction codes of a microcomputerbut since the LSI-11 microprocessororiginated from the PDP-11 family it isa multi-microprocessor (Avtar, 207). The factthat the LSI-11 microprocessor is a multi-microprocessormeans that many other mi-croprocessors are used in conjunctionwith the LSI-11 to function properly (Avtar,207). The LSI-11 microprocessorhas a direct processing speed of 16-bit word and 7-bit data, however the improved LSI-11/22can directly process 64-bit data (Titus, 131). The average time that the LSI-11 and LSI-11/2process at are 380 nanoseconds, whilethe LSI-11/23 is clocked at 300 nanoseconds(Titus, 132). There are some greatstrengths that lie in the LSI-11 family,some of which are the efficient way at whichthe microprocessor processes and the abilityto run minicomputer software which leadsto great hardware support (Avtar, 179). Domestic Violence Essay PaperThe next family of microprocessorwhich was fabricated for the microcomputeris the MC68020 32-bit microprocessor whichis based on the MC68000 family. Theother microprocessors that are includedin this family are the MC68000, MC68008,MC68010 and the MC68012 (Avtar, 302). Before going into the types of componentsthat this microprocessor contains, itshould first be know that the making of theMC68020 has been the product of 60 man-yearsof designing including the manufac-turing of the High-density ComplementaryMetal Oxide Semiconductor giving the mi-croprocessor high speed and low resistanceand heat loss (Avtar, 302). Because of allthe work that was put into the MC68020and its other related microprocessors, it is anextremely complex microprocessor. The MC68020 operates in two modes, these arethe user mode(for application programs)or the supervisor mode (the operating systemand other special functions) (Mitchell,155). The user and supervisor modes all havethere own specific registers to operatetheir functions. The user programming has 1732-bit address registers, and an 8-bitregister (Mitchell, 155). Then the supervisor pro-gramming has three 32-bit, an 8-bit andtwo 3-bit registers for small miscellaneousfunctions (Mitchell, 155). All ofthese registers within the two modes are split up intodifferent groups which would hold differentinformation as usual, but this set up ofregisters gives the microprocessors a20 32-bit information storing capacity. The next family of microprocessoris Intels 80386 and 80486 families. The80386 and 80486 were mostly over all betterthen the other microprocessors beingmade by the different companies in theindustry at this time, simply because Intel isnow the leading microprocessor producerin todays market. The 80386 was a productthat evolved from Intels very first microprocessor,the 8-bit 8080 (Mitchell, 85). Thennext came the earlier mentioned 16-bit8086. The reason why Intel did so well in themarket for microprocessors was becauseevery microprocessor that they made wascompatible with the previous and future(Mitchell, 85). This means that if a piece ofsoftware worked on the 8080 then it workedon the future microprocessors and vice-a-versa. Not only did Intel look forwardbut they looked back. The main differencebetween the 80386 and the other 32-bitmicroprocessors is the added feature of a bar-rel shifter (Mitchell, 88). Thebarrel shifter allowed information to switch places mul-tiple times in the r egisters within asingle cycle (Mitchell, 88). The microprocessorcontains 8 general purpose 32-bit registers,but with the barrel shifter that is increasedto the equivalent of a 64-bit microprocessor. For the most common 20MHz 80386microprocessor the run time for each cycleis 59 nanoseconds, but for a 33MHz mi-croprocessor the cycle time is reducedto 49 nanoseconds. The next 32-bit microprocessor in marketare AT;Ts WE32100 and 32200(Mitchell, 5). These microprocessorsalso needed six peripheral chips in order to run,these are termed: Memory Management Units,floating point arithmetic, Maths Accel-eration Units, Direct Memory Access Control,and Dynamic Rand Access MemoryControl (Mitchell, 5). These microprocessorsapart from the microprocessors all workan important part of processing the datathat comes through the microprocessor. Thedifference from this microprocessor andthe others is because the WE32200 addressinformation over the 32-bit range withthe help of a disk to work as a slow form ofmemory (Mitchell, 9). The WE32200microprocessor runs at a frequency of 24MHz(Mitchell, 9). The 16-bit and 32-bit microprocessors area mere page in the great book ofprocessor history. There will bemany new and extremely different processors in thenear future. A tremendous amountof time and money have been put into the makingand improving of the microprocessor. The improving and investment of billions ofdollars are continually going toward thecause of elaborating the microprocessors. Theevolution of the microprocessor will continueto evolve for the better until the timewhen a much faster and more efficientelectronic device is invented. This is turn willcreate a whole new and powerful generationof computers. Hopefully this paper hasgiven the reader some insight into theworld of microprocessor and how much workhas been put into the manufacturing ofthe microprocessor over the years.

US History of US health care

Table of Contents Health insurance in US History of Laser Eye Surgery Michael DeBakey: Father of cardiovascular surgery Health care reforms in the U.S Vaccination: A preventive measure for all ages References Health insurance in US Health care is arguably one of the most pressing concerns of governments all over the world. All developed countries are characterized by having elaborate healthcare systems which are in place to ensure that majority of the population has access to medical care when they need it. Advertising We will write a custom essay sample on US History of US health care specifically for you for only $16.05 $11/page Learn More Arguably, health care insurance is a relatively new trend in the US. Before 1920, doctors and medical practitioners did not have many insights on diseases and curative techniques. As such, the cost of receiving medical care was relatively low and affordable to many Americans. However, as ore discoveries were mad e and new techniques of delivering healthcare services emerged, the cost of receiving the same began to increase. As a result, many people could not afford quality care due to financial constraints. To this effect, private companies started offering health plans to their employees. However, the healthcare plans only covered against accidents related to travel by rail or water. However, these plans paved way to more comprehensive covers that catered for other illnesses and injuries. In 1847, Massachusetts Health Insurance of Boston became the first company to offer group policies that gave comprehensive cover to its clients. Consequently, in 1890, insurance companies started offering individual disability and illness policies to their clients (Northern California Neurosurgery Medical Group, 2007). By 1929, group insurance covers had gained prominence in the US. Baylor Hospital was the first organization to enter into a contract with a group of teachers from Dallas. This agreement ai med at ensuring that these teachers receive room, board and medical services from the hospital. The teachers on the other hand agreed to pay a monthly fee in exchange for these services. Soon after, several life insurance companies joined this seemingly lucrative field. A precursor to future health care insurance schemes in America was Blue Cross which was the first innovation that changed the shape of the health care system in America. This plan developed in 1930 advocated the payment of small premiums that would be cover the medical costs should one be hospitalized. Advertising Looking for essay on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More The rationale behind this scheme was that while huge medical bills were unaffordable to most people, little deductions over a long period of time were affordable to majority of the population (Kooijman, 1999). This form of prepaid service was beneficial to both the hospital and th e consumer especially in times of economic difficulties since neither party had to worry about the hospital bill being cleared. During the Second World War, employers started offering insurance cover to their employees mostly as a way of attracting and retaining the employees. However, this created a trend and became almost mandatory as strong trade unions started to negotiate for insurance packages for their employees. Northern California Neurosurgery Medical Group, (2007) notes that as of 1960, private health insurance was deeply entrenched into the American health care system and over 70% of the citizens had some form of cover. In 1965, the U.S government created the Medicare and Medicaid programs with the aim of subsidizing the escalating cost of medical services. This was mainly due to the fact that private sources catered for 75% of their medical costs. At this rate, many citizens could not cover their medical costs. However, these programs proved to be effective because as at 1995, individuals and companies enjoyed reduced costs since they only paid about half of their medical bills while the government covered the rest through these programs (U.S. Department of Health Human Services, 2009). History of Laser Eye Surgery In the past few decades, inventions and breakthrough scientific discoveries in the biological field have resulted in the prevalence of access to sophisticated equipment and advanced diagnostic procedures that were once only in the reins of research institutes and few specialist hospitals. One of these technological advancements has been in the form of laser eye surgery. Documented evidence indicates that over the past one hundred years, there has been an increased interest in refractive surgery. By 1898, Lans, a prominent professor of Ophthalmology had laid out the basic principles of radial keratotomy. Advertising We will write a custom essay sample on US History of US health care specifically for you for only $16.05 $11/page Learn More Before 1970, various eye specialists adopted different methods and techniques to treat eye related problems. However, there were many complications regarding these techniques and in some cases, they made the situation worse than it was before. The most significant breakthrough was made in Russia in 1970’s. This was in a case whereby Dr. Fyodorov was treating a boy whose glasses had broken and damaged his eyes (Taylor, 2011). This situation gave the doctor an opportunity to test the effectiveness of radial keratotomy. After the surgery, the doctor documented that the boy’s refractions were significantly less than they were before the injury. This discovery prompted him to do more research on the process. As a result, he came up with a formula that made refractive surgery more predictable than it was before (Taylor, 2011). It was not until 1978 that American ophthalmologist Dr. Leo Bores brought back the necessary technology for this surgery into America (LaserSurgeryForEyes.com, 2002). It should be noted that until 1970, lasers were primarily used to produce silicone computer chips in America. The mode of production was referred to as Excimer laser process. After further research, it was discovered that the Excimer laser process could be used to remove damaged tissues without the risk of heat damaging the surrounding tissues. This discovery was made in 1982 by three members of an IBM research team. Soon after, this technique was applied in an array of medical procedures and treatments. However, it was not until 1982 that Dr. Steven Trokel, an American ophthalmologist based in New York first conducted the first eye surgery using this technique (Laser Eye Surgery, 2009). The following decade saw scientists and researchers devote significant efforts towards perfecting the technique. It was not until 1996 that the government finally approved laser eye surgery in US (Laser Eye Surgery, 2009). This approval led to an increase in eye treatment options. It should be noted that before this approval, some eye treatment options would leave the patient immobile for a long period of time (six or more weeks), and the surgeries were very risky. However, laser eye surgery presented practitioners and patients with a less risky, time saving, efficient and convenient option to correcting eye problems. Arguably, if you were among the 80% of Americans who require vision correction, the only option before the approval of laser eye surgery would have been either glasses or contact lenses.

More research is being carried out to improve the technique and facilitate better and safer eye correction services in the future. Michael DeBakey: Father of cardiovascular surgery A life well lived is one that is lived in such a way that it makes a positive difference to others.throughout history, different people have been credited for their works in regard to making a difference in the lives of others. Michael DeBakey is among such people in the medical arena. Born in 1908, in Los Angeles, this American surgeon helped develop various treatments and surgical procedures that have revolutionized the medical practice up to date. Before he died of natural causes in 2008, Michael DeBakey had performed heart operations in excess of 60,000. In addition, he had published more than 1,500 scientific publications tha t helped other practitioners understand and treat various medical phenomenons. His works have helped add decades of years to some of his patients in America and abroad. Similarly, he has trained many renowned surgeons across the world. As regarding to his achievements and contributions in the healthcare sector, Michael DeBakey invented the roller-pump in 1932 (NNDB, 2011). Twenty years later, this invention became an integral component during the development of the heart-lung machine which enabled cardiovascular surgeons to conduct open-heart surgeries. NNDB (2011) further document that in 1953, Michael DeBakey â€Å"introduced improved Dacron and Dacron-velour artificial grafts to replace damaged arteries†. He was among the leaders in the development of artificial arteries and introduced the concept of bypass surgery in the healthcare sector (NNDB, 2011). He is also credited for the creation and development of the Mobile Army Surgical Hospitals (M.A.S.H) concept, which help ed save many lives during the Korean and Vietnamese wars (wic, 2011). Arguably, Michael DeBakey is best known for inventing the ventricular assist device (VAD) that is commonly referred to as the artificial heart. He invented this device in 1968 so that it would help patients whose hearts had weak cardiovascular muscles pump blood by assisting the main pumping chamber. It should be noted that this invention was never intended to replace the full heart but merely to offer assistance to weakened hearts. However, it paved way for more research and consequently, the first artificial heart was developed and implanted into a human being a year later. This operation was carried out in 1969 by Dr. Denton Cooley who was a former colleague of Michael DeBakey (NNDB, 2011). In his pursuit for perfection, Michael DeBakey together with another colleague invented the Jarvik artificial heart (NNDB, 2011). This heart was first fitted into a human being in 1982. Later on in the 90s, Michael DeBakey in collaboration with NASA developed a miniaturized heart pump. This pump was so small that it could easily and comfortably be implanted in a child. These are among the key contributions that the renowned surgeon and physician made during his lifetime. Besides this, he was best known as being a Good Samaritan, a pioneer and a dedicated statesman who strived to ensure that every person had a chance to live a long and health life. The Wic website states that â€Å"Dacron arteries, arterial bypass operations, artificial hearts, heart pumps and heart transplants are common procedures in today’s medicine, thanks to Dr. DeBakey (wic, 2011). This statement is true as has been elaborated in this essay. Health care reforms in the U.S The US government has always taken a keen interest in the healthcare provision of its citizens. Kovner, Knickman and Jonas (2008) state that this idea of government involvement in the health concerns of the citizens can trace its existence from as far back as the 17th century. It is recorded that as early as the beginning of the 19th century, a majority of American citizens were worried about the affordability and availability of health care. It is for this reason that the public healthcare option was conceived in the late 1800s. However, it was in the era of President Theodore Roosevelt that health reforms took a definite shape. His monumental declaration that â€Å"Nothing can be more important to a state than its public health: the state’s paramount concern should be the health of its people.† (Sebelius, 2009) highlighted his dedication towards achieving a system that he perceived would afford the population the best opportunity to acquire health care. Roosevelt’s continuous commitment to a national health insurance plan through from 1912 was one of the key factors that shaped the public health insurance policies in the United States. Kooijman (1999), states that as of 1935, the efforts for national heal th insurance were greatly derailed by medical practitioners who were greatly opposed to the scheme. This opposition stemmed from a misguided perception of what health insurance implied. The practitioners mistook the national health insurance for a socialistic system of medical practice whereby the government would limit the fee they received for their services. This widespread lack of support for the system led to the exclusion of a national health insurance plan in the social security act thus dealing a great blow to the public option. In 1994, the then US President Clintons made a move to provide universal coverage through an employer mandate in 1994 (Singer, 2009). However, his administration was against a public insurance option which he deemed to be too expensive. President Bush also dealt a blow to the universal health care system by his move to veto a proposed health insurance program. He perceived the plan as a move towards a socialized health care system which would be unw anted since it would end up benefiting people who did not need any assistance. The public option received a new lease of life with the election of President Obama in 2008. One of his major campaign policies was the wide spread reforms in the health care system. This has been perceived to be one of the major factors that led to his election. President Obama sees a shift towards a healthcare system that is both affordable and places value on quality service as the solution to the troubled system currently in place. His emphasis is on the affordability of health care for all American citizens through the adoption of a public option that would offer competitive prices to the people and therefore greatly regulate the health insurance market. However, his aim towards this has been marred by opposition from senators and financial institution. Vaccination: A preventive measure for all ages Over the past few years there have been an increase in the number of diseases that affect human bein gs. As such, researchers and medical experts have dedicated most of the available resources to ensure that both preventive and curative measures are put in place in a bid to avoid further spread of the various diseases that pose a serious risk to the human race. The major challenge being faced globally is creating awareness of the diseases and controlling or containing their spread. Throughout history, vaccination has proven to be an effective strategy against many life threatening infections and ailments. In the United States, vaccines were used to eradicate life-threatening conditions such as polio and small pox. Arguably, the rise and fall of small pox is among the best feat when it comes to medical breakthroughs. The origin of the disease is not well known but it is believed to have originated from Africa and spread through other parts of the world. However, it was reported in most parts of America in the 17th and the 18th centuries. The fall of the scourge came through the r ealization that the people who survived the disease became immune for life. This knowledge led to the development of the process known as variolation (Brannon, 2005). This process involved infecting a healthy person with a mild form of small pox in the hope that he/she would develop some immunity against the disease in the future. The process worked and people underwent this process. Statistics indicate that 2-3% of people who underwent this process died of smallpox (Brannon, 2005). However, the majority survived and the number of people infected by this disease reduced significantly. Edward Jenner is credited for being the inventor of the first small pox vaccine (Brannon, 2005). The English physician observed that milkmaids who developed cowpox were less vulnerable to small pox. As a result, in 1796, the physician took a pustule sample of the cowpox infected maid and inoculated an 8 year old boy with it (Brannon, 2005). Six weeks later, Jenner exposed the subject to smallpox. To his own amazement, the boy did not show any symptoms of the disease. It is from this result that Jenner came up with the word vaccine. The word came from the Latin word ‘vaca’, which means cow (Brannon, 2005). Initially, many practitioners and people criticized his work but as his success rate increased; his method was rapidly adopted by other practitioners. Statistics indicate that at the wake of 1800, more than 100,000 people were already vaccinated against the disease. In America, the last outbreak of the disease was reported in 1949 (Brannon, 2005). The outbreak only affected eight people and claimed one life. However, the disease still claimed lives in other parts of the world. As a result, the world health organization initiated a campaign in 1967 (Brannon, 2005). The main purpose of this campaign was to promote awareness and eradicate smallpox in all regions of the world. This goal was realized in the ten years that followed. This was attributed to the massive vaccination efforts that ensued during that period (Brannon, 2005). Consequently, the last case of smallpox was reported in Somalia in 1977. However, measures were taken to ensure that everyone was vaccinated against the disease. Subsequently, in 1980, the World Health Assembly finally declared the world free from this killer disease (Brannon, 2005). It should be noted that by the year 1972, America had already vaccinated all its citizens but continued to vaccinate military personnel who were at risk of infection due to the nature of their job (Brannon, 2005). Vaccinations have been used to create immunity against other diseases. As a result, the infant mortality rate has decreased significantly across the world as compared to the situation a century ago.

Sociological Autobiography Research Paper Example Sociological Autobiography Paper Sociological Autobiography Paper Essay Topic: Autobiography of My Mother In Brooklyn, New York on July 10th, 1979 that was the day I decided to make my grand entrance into this world. At birth I was given an ascribed status of an African American female, which would play an important role in my life as I grew older. My parents were married and very young at the time of my birth. My maternal grandparents thought it would be best if I lived with them while my parents worked and went to school. This arrangement worked out for several years and seemed beneficial for both my parents and I. I lived with my grandparents until I was about 5 years old or when my mom and dad divorced. As a result of the divorce, my mother became a single parent. My mother raised me on her own until she met Mr. Wayne. After the divorce, my dad lost contact with me, our relationship became estranged. During that time my father earned his achieved status as a dead-beat dad. That status would soon change when my father met his second wife. My step-mother expressed to my dad if he wanted to be with her, he has to be involved in his child’s life. She has been a blessing to me from the beginning of their relationship. My father reconciled any differences he had with my mother and began to rebuild our father/daughter relationship. My mother and Mr. Wayne eventually got married and moved in together. Growing up in a blended family had it pros and cons. I was an only child, on my mom’s side for about 10 years until my brother Zuri came along in 1988. I didn’t have siblings on my dad’s side until 1996 when my brother Terrell was born and 1999 when my sister Sharina was born. My childhood upbringing definitely had a tremendous force on how my future adult life would turn out. My mother, father, and grandparents all had an impact on my outlook of life. They all worked very hard to provide the best for our family. I grew up in what sociologists would the call the working lower-middle class. Although life with my primary group was great at 16 years old, I began to get tired of the switching of the households every other weekend. It was frustrating especially being a product of a blended family. I had social ties with my friends at school and I had a boyfriend with whom I thought I was madly in love with. My social network was increasing and it was important for me to maintain those relationships with my secondary groups or at least I thought it was. Growing up in New York City offered me an opportunity to live in an environment with no obstructions. I was able to connect with a diverse population on a daily basis. I had friends from various ethnic backgrounds.
