Evolution of the processor unit
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 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 remainder of the paper will discuss the 32-bit microprocessor series. There are many different types of companies of which all have their own family of processors. The difference from this microprocessor and the others is because the WE32200 address information over the 32-bit range with the help of a disk to work as a slow form of memory (Mitchell, 9). Like so many of the other processors the 8086 is register oriented with fourteen 16-bit registers, eight of which are used for general processing purposes (Avtar, 19). At this time in the evolution of microprocessors come the 32-bit register, which obviously has double the capacity to hold information for the microprocessor. Then the supervisor pro- gramming has three 32-bit, an 8-bit and two 3-bit registers for small miscellaneous functions (Mitchell, 155). The 8086 was introduced in early 1978 by Intel (Avtar, 19). The evolution of the microprocessor will continue to evolve for the better until the time when a much faster and more efficient electronic device is invented. This means that if a piece of software worked on the 8080 then it worked on the future microprocessors and vice-a- versa. 3MHz and even some variations of the original microprocessor where made to go up to 4MHz (Avtar, 115). The first 32-bit microprocessor in the microprocessor industry that will be dis- cussed is the series 32000 family and was originally built for main-frame computers. The other microprocessors that are included in this family are the MC68000, MC68008, MC68010 and the MC68012 (Avtar, 302). The user programming has 17 32-bit address registers, and an 8-bit register (Mitchell, 155).
