EVOLUTION OF MICROPROCESSORS INTRODUCTION A microprocessor incorporates the functions of a computer’s central processing unit (CPU) on a single integrated circuit (IC)‚or at most a few integrated circuits. It is a multipurpose‚ programmable device that accepts digital data as input‚ processes it according to instructions stored in its memory‚ and provides results as output. It is an example of sequential digital logic‚ as it has internal memory. Microprocessors operate on numbers and

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

It acts as the brain of the computer system. As technology has progressed‚ microprocessors have become faster‚ smaller and capable of doing more work per clock cycle. Sometimes‚ microprocessor is written as µP. ( µ

Muganda AU ID: 0719604 May 3‚ 2001 -2- EVOLUTION OF THE MICROPROCESSOR INTRODUCTION The Collegiate Webster dictionary describes microprocessor as a computer processor contained on an integrated-circuit chip. In the mid-seventies‚ a microprocessor was defined as a central processing unit (CPU) realized on a LSI (large-scale integration) chip‚ operating at

The Evaluation of the Microprocessor. The microprocessor has changed a lot over the years‚ says (Michael W. Davidson‚http://micro.magnet.fsu.edu/chipshot.html) Microprocessor technology is progressing so rapidly that even experts in the field are having trouble keeping up with current advances. As more competition develops in this $150 billion a year business‚ power and speed of the microprocessor is expanding at an almost explosive rate. The changes have been most evident over the last decade

6800 * After seeing the success of Intel ’s 8-bit 8008 microprocessor‚ Motorola introduced its first 8-bit microprocessor‚ the 6800‚ in 1974. The 6800 became more prevalent due in part to the system oriented support hardware that Motorola introduced with the 6800. The 6800 was competing in the market with the Intel 8080. The 6800 was used in some early home computer kits‚ the Tektronix 4051 Graphics Computer System and in a microprocessor trainer sold by Heathkit. The 6809 * Around 1977‚ Motorola

8 1 Introduction: At their birth microprocessors came with extravagant claims that later proved to be appropriate. Such a claim was: “The microprocessor represents truly low-cost computing . Its economics are so compelling that microcomputers are serving not only in many applications where computing power was previously too costly but also in applications where . . . computer control was formerly unthinkable” [1] which shows us that the microprocessor was built as the cheapest and most accessible

The history of the microprocessor begins with the birth of the Intel 4004‚ the first commercially available microprocessor. The roots of this development can be traced directly back to the inventors of the transistor. In 1955‚ William Shockley founded Shockley Semiconductor in Palo Alto‚ California (arguably the birth of Silicon Valley). This company eventually employed Gordon Moore and Robert Noyce‚ who left with others to form Fairchild Semiconductor in 1957. While at Fairchild‚ Noyce played a
