Basic Concepts of Microprocessors -Differences between: – Microcomputer – a computer with a microprocessor as its CPU. Includes memory, I/O etc. – Microprocessor – silicon chip which includes ALU, register circuits & control circuits – Microcontroller – silicon chip which includes microprocessor, memory & I/O in a single package. Definition of the Microprocessor The microprocessor is a programmable device that takes in numbers, performs on them arithmetic or logical operations according to the program stored in memory and then produces other numbers as a result. 1.

What is a Microprocessor? • The word comes from the combination micro and processor. – Processor means a device that processes whatever. In this context processor means a device that processes numbers, specifically binary numbers, 0’s and 1’s. • To process means to manipulate. It is a general term that describes all manipulation. Again in this content, it means to perform certain operations on the numbers that depend on the microprocessor’s design. 4. What about micro? • Micro is a new addition. – In the late 1960’s, processors were built using discrete elements. • These devices performed the required operation, but were too large and too slow. – In the early 1970’s the microchip was invented. All of the components that made up the processor were now placed on a single piece of silicon. The size became several thousand times smaller and the speed became several hundred times faster. The “Micro”Processor was born.
