Microprocessors Evolution Essays - Microprocessors, 16-bit, Motorola

Microprocessors Evolution Only once in a lifetime will a new invention come about to touch every aspect of our lives. Such a device that changes the way we work, live, and play is a special one, indeed. The Microprocessor has been around since 1971 years, but in the last few years it has changed the American calculators to video games and computers (Givone 1). Many microprocessors have been manufactured for all sorts of products; some have succeeded and some have not. This paper will discuss the evolution and history of the most prominent 16 and 32 bit microprocessors in the microcomputer and how they are similar to and different from each other. Because microprocessors are a subject that most people cannot relate to and do not know much about, this paragraph will introduce 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 are or how much storage is available for the mi- croprocessor (Aumiaux, 3). The microprocessor has a memory address such as A16, and at this address the specific commands to the microprocessor are stored in the memory of the computer (Aumiaux, 3). So with the 16-bit microprocessor there are 576 places to store data. With the 32-bit microprocessor there are twice as many places to store data making the microprocessor faster. Another common term which is mentioned frequently in the paper is the oscil- lator or the time at which the processors "clock" ticks. The oscillator is the pace maker for the microprocessor which tells what frequency the microprocessor can proc- ess information, this value is measured in Mega-hertz or MHz. A nanosecond is a measurement of time in a processor, or a billionth of a second. This is used to measure the time it takes for the computer to execute an instructions, other wise knows as a cy- cle. There are many different types of companies of which all have their own family of processors. Since the individual processors in the families were developed over a fairly long period of time, it is hard to distinguish which processors were introduced in order. This paper will mention the families of processors in no particular order. The first microprocessor that will be discussed is the family of microprocessors called the 9900 series manufactured by Texas Instruments during the mid-70s and was developed from the architecture of the 900 minicomputer series (Titus, 178). There were five dif- ferent actual microprocessors that were designed in this family, they were the TMS9900, TMS9980A, TMS9981, TMS9985, and the TMS9940. The TMS9900 was the first of these microprocessors so the next four of the microprocessors where simply variations of the TMS9900 (Titus, 178). The 9900 series microprocessors runs with 64K memory and besides the fact that the 9900 is a 16-bit microprocessor, only 15 of the address memory circuits are in use (Titus, 179). The 16th address is used for the computer to distinguish between word and data functions (Titus, 179. The 9900 series microprocessors runs from 300 nanoseconds to 500 ns from 2MHz to 3.3MHz and even some variations of the original microprocessor where made to go up to 4MHz (Avtar, 115). The next microprocessor that will be discussed is the LSI-11 which was pro- duced from the structural plans of the PDP-11 minicomputer family. There are three microprocessors in the LSI-11 family they are 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 the LSI-11 family of microprocessors and other similar microprocessors of its kind is they have the instruction codes of a microcomputer but since the LSI-11 microprocessor originated from the PDP-11 family it is a multi-microprocessor (Avtar, 207). The fact that the LSI-11 microprocessor is a multi-microprocessor means that many other mi- croprocessors are used in conjunction with the LSI-11 to function properly (Avtar, 207). The LSI-11 microprocessor has a direct processing speed of 16-bit word and 7- bit data, however the improved LSI-11/22 can directly process 64-bit data (Titus, 131). The average time that the LSI-11 and LSI-11/2 process at are 380 nanoseconds, while the LSI-11/23 is clocked at 300 nanoseconds (Titus, 132). There are some great strengths that lie in the LSI-11 family, some of which are the efficient way at which the microprocessor processes and the ability to run minicomputer software which leads to great hardware support (Avtar, 179). Although there are many strengths to the LSI- Microprocessors Evolution Essays - Microprocessors, 16-bit, Motorola Microprocessors Evolution Only once in a lifetime will a new invention come about to touch every aspect of our lives.

Research Design Discussion Example

Research Design Discussion Example Research Design Discussion – Coursework Example Research Design Discussion Research Designs Design is the structure of any  scientific  work that gives direction, and  systemizes  the research. In view of the  second  responders program: a coordinated police and social service response to domestic violence, it is clear that the researchers employed the quasi experimental design; this being a both qualitative and quantitative method (Gribbons & Herman, 1997). Field findings of the researchers  are based  on two waves of victims: women who received  second  responder intervention, and women who received police intervention. The experimental and control groups  were defined  by geographical boundary, a wide range of  demographical  data  was collected. The  second  responders program  was implemented  in two of its four police precincts’ in Richmond. Interview findings  were presented  in four broad areas: services provided by police and responders, attitude towards police and second r esponders, the  probability  of receiving follow up, and likelihood of receiving protection.The study opted for a quasi research design over a true experimental design  because  the true experimental design tend to  prove  or reject a hypothesis mathematically with statistical analysis.  It has more of a quantitative design  method  reason  for this could be due to  random  assigning of groups that  are approached  in the later design (Gribbons & Herman, 1997). Again the true experimental design demands for  viable  control group, this design suggest that only one variable can be manipulated and tested yet we see that the research involved testing of more than one variable. True experimental design also involves a process whereby the tested subjects  are randomly assigned  to either experimental or control groups. However, what we see in the study is that the experimental group  was drawn  from the first and second precincts whereas the contro l group from third and fourth precincts.ReferenceGribbons, B., & Herman, J.

A critical analysis of the concept of addiction with reference to drug Essay

A critical analysis of the concept of addiction with reference to drug misuse - Essay Example those that are harmful for health such as Marijuana, cocaine, opium, hallucinogens and many others, people become addicted to the usage of those drugs (Giannini 1997). The drugs that are prescribed by the doctors do not appear to be harmful for the users but those that are harmful and are used without the help of any doctor or in terms of self-medication come up with negative consequences in terms of health and life security. The drugs that are prescribed the doctors can also be considered as abusive when a person gets addict to the drugs. After being addicted, the tolerance level of a person increases due to which, an increased amount of drug is required by the person that can harm him/her in terms of his/her health (Kalivas and Volkow 2005). Drugs that are considered as causing addiction are mostly illegal drugs such as cocaine, nicotine, caffeine, heroin, Marijuana, opium and many others (Goodman 1990). When people start misusing the drugs to a harmful level, they become addict to the drugs due to which, they have to depend on the drugs for their physical sustenance and normal health. This dependency on drugs is not considered a negligible issue as the number of people who can be called as dependent on drugs and addicts are increasing day by day (Nestler and Malenka 2004). The addiction to drugs causes many dangers for the health of men as well as women. Illegal usage of drugs causes such consequences that are not facilitating for the drug users. Women are categorized as mostly disadvantageous in terms of misuse of drugs because of their future or current pregnancy (Giannini 1997). The misuse of drugs causes many types of diseased effects in the users due to which, they are unable to lead normal lives and face many health issues. People always seek out for drugs in spite of knowing the dangerous consequences being caused by drugs because of their becoming addicts. People use drugs on a regular basis due to many factors. Many people make use of drugs because

HOW TO FIND A GOOD SOURCE FOR RESEARCH PAPER Essay

HOW TO FIND A GOOD SOURCE FOR RESEARCH PAPER - Essay Example As Belk (72) argued, primary research sources offer credible evidence that is produced in the historical period under investigation and relates to the actual findings of the researcher. Therefore, the best criterion in choosing a research source is determining whether the source is a primary or secondary source. Moreover, Levy and Ellis (181) noted that methodological reviews of past literature are an important undertaking in research. Methodological reviews are systematic research findings of what has been covered in the past and are critical in initiating a new research. As such, using studies with such methodological reviews would ensure the researcher stands a better place to formulate a new research armed with ample knowledge of what has been done before. Therefore, studies with methodological reviews are some of the best sources to choose before undertaking any research paper. Moreover, the date of publication of a research source may affect the quality of the source used in re search papers. However, the need to seek recent sources depends on the topic of study. Recent studies have updated and current findings, which might be a good basis to formulate a research paper (Perdue Owl, 2013). For instance, when undertaking a research paper on technology, choosing the most current source guarantees crucial information about the current technology, which may not be found in a source published one or two years

How will e-health affect patient participation in the clinic pros and Essay

How will e-health affect patient participation in the clinic pros and cons - Essay Example E-health is defined as â€Å"a new term used to describe the combined use of electronic communication and information technology in the health sector OR is the use, in the health sector, of digital data-transmitted, stored and retrieved electronically-for clinical, educational and administrative purposes, both at the local site and at a distance† (WHO Regional Office for the Eastern Mediterranean, 2003). When it comes to clinical purposes, e-health makes easy it to manage and update medical records, allows electronic prescribing of medications, and makes patient management less demanding. E-health also fosters learning. Patients can access information about their condition and treatment options. There are also online support groups for people with similar conditions through e-health. Doctors can also use e-health for their continuing medical education. ICT health tools can also be used for organizational purposes. Scheduling of appointments and monitoring of laboratory results are made easier with e-health. The development of e-health has made it possible for healthcare professionals to give and for patients to receive quality, effective, and efficient healthcare services. Through the use of various e-health tools and services, communication and health management are a lot quicker and easier. Information is easily accessible and there is less stress on both healthcare providers and patients. E-health tools allow healthcare providers to care for the patients based on each one’s individual needs, allowing them to give care that is patient-centered. For patients, e-health tools provide them with information regarding their condition and encourage them toward self-care. E-health has evolved a lot and many consider it to be an indispensable tool in the industry of healthcare. Laboratories rely heavily on computers for analysis and many diagnostic

The company is now making efforts to reduce debt in order to establish a solid financial profile by March 2012. Towards this goal, the company announced a policy to constrain capital investment, particularly in the semiconductor business. Standard Poors considers Toshibas conservative financial policy to be further evidenced by the implementation of a number of planned financial activities. These include capital enhancement through an increase in common stocks and the refinancing of short-term debt by the issuance of subordinated bonds. Standard Poors will closely monitor whether the company can improve its financial indicators as planned, through the consistent reduction of fixed costs and capital investments. Lack of manpower After four months of struggle and weeks of intense negotiations, workers and management at Toshiba Consumer Products Indonesia reached a settlement: 682 workers will be reinstated, but 15 local union leaders will not get their jobs back. Over leveraged financial position Year over year, Toshiba Corporation has seen revenues fall from $80.4B to $76.6B. This along with an increase in the cost of goods sold expense has led to a reduction in the bottom line from $1.7B to $925.7M. Ubiquitiouegory, products, services Cloud services will become truly ubiquitous, omnipresent. It is the broader access to most recent content and information plus the benefit of a vast social community contributing to its discovery and consumption adding, recommending, rating and prioritizing content and information that will make cloud services an increasingly indispensable element in consumers evolving digital lifestyle. Sun Zi said: When victory is long overdue, weapons will be blunt and the morale (and motivation) of the troops will be adversely affected. In war, it is better to go for swift victories rather than engage in prolonged military campaigns. Sun Zi also said: Therefore, generals who do not thoroughly comprehend the inherent dangers of deploying troops are unlikely to understand the advantages of using troops. Opportunities Market Recently Toshiba just launch the 12 new products in the Bangladesh. Bangladesh have a large population approximately 160 million. Toshiba has working with Smart Technologies BD Limited (STBL) Bangladesh Company since last 3 years. In this 3 year, Toshiba Company found that Bangladesh market impressive increase in term of sales volume and growth. Bangladesh is developing and has high potential in market. Global expansion It can let the profit or income of the Toshiba Company to increase or growing the market value of the Toshiba Company among the world. The popularities can also increase by this way. Without affecting quality and customer service, global expansion can maximizing profitability in all areas of the Toshiba Company. For instance, by developing the new marketing strategies in those regions, it can make let Toshiba Companys loyalty customers to buy their products. Global expansion can also help to leads to leveraging of expertise. With global expansion, leveraging any know-how or expertise in overseas production is prudent. Future plans Toshiba aim to double its annual profit in three year. The worlds No.2 maker of NAND flashes chips, behind the Samsung electronics. The firm is going to shift its focus to emerge economies and growing market after the demand for television fall dramatically than expected in the previous year. Besides that, Toshiba Company also interested in making money through nuclear power, they plan to buy 20 percent of share from the U.S nuclear power company in the next January. Toshiba is going to invest about $4.3 billion dollar to build new flash memory facility, in order to catch up the leader Samsung electronics, aiming to triple its manufacture capacity. Moreover, Toshiba plan to roll out a home storage battery system that can keep the appliances running for a good part all the day long. Toshiba developed a storage battery system that makes use of the Toshiba technology for rechargeable batteries. This storage battery can work up to 12 hour. Threats Competition Being an electronic company, in this environment of course there will be a lot of competitor. For example, the competitor for the Toshiba Company likes Samsung, Apple, HP, Dell, and other company that focus electronic production. These companies have created threats for the Toshiba Company. The tablets that made by Toshiba is not really attracted by consumer, because Apple and Samsung are leading on this market products. Besides that, Toshiba main production is notebook, although this is their priority product, but a lot of competitor also produces various type of notebook. Although they made a quality, productivity and user friendly notebook, but Toshiba still behind the other competitor that leading them by brand name position on customer heart. External changes This changes is depends on the government taxes and politics in the certain country that the Toshiba company invest in. First and foremost, government taxes and politics have created a burden to all company. As taxes increase its have the same effect that the company need to cover the cost of the good that rise such as electricity and input, all company are established because their purpose is profit.

Compare and contrast the music of the Medieval, Rennaissance, and Baroq

Music throughout the ages has changed dramatically. Starting in the Medieval period, from 400-1475, music was in the form of what is called the Gregorian chant. Instruments were very rarely used at this time. Since songs during this period were either troubadour or trouvere these chants had no real harmony. One example of this type of medieval composition is â€Å"Viderunt Omnes† by Leoninus. Like most Gregorian chants the texture of this piece is monophonic and polyphonic. â€Å"Viderunt Omnes† is a typical Gregorian chant in that it uses diatonic, not chromatic notes of the scale. Musical compositions during the Medieval period was made mostly by members of the church for the church. It was and is a very slow and steady movement that was meant to create a feeling of peace for worship purposes. As time passed and music continued to evolve what is known as the Renaissance period emerged from 1475-1600. Music during this period was still written with worship as its intentions. Where the Medieval period had no harmony the Renaissance period introduced the use of a constant chord to form the building block of the different pieces. A good example of this period of music is â€Å"Ave Maria† by Josquin written in 1485. The many different voices the repeat the same words create a process called imitation. This particular chant is capella, meaning that it is performed by voices alone and has no musical accompaniment and with all the voices entering at different times but in harmony counterpoint i...
