Microprocessor

Features Microprocessor

✴A silicon chip that contains a CPU.
In the world of personal computers, the terms microprocessor and CPU are used interchangeably.
At the heart of all personal computers and most workstations sits a microprocessor.
Microprocessors also control the logic of almost all digital devices, from clock radios to fuel-injection system for automobiles.
✴
❰ Three basic characteristics differentiate microprocessors:
❱► Instruction set: The set of instructions that the microprocessor can execute.► bandwidth : The number of bits processed in a single instruction.► clock speed : Given in megahertz (MHz), the clock speed determines how many instructions per second the processor can execute.
✦In both cases, the higher the value, the more powerful the CPU.
For example, a 32-bit microprocessor that runs at 50MHz is more powerful than a 16-bit microprocessor that runs at 25MHz.
✦
✦In addition to bandwidth and clock speed, microprocessors are classified as being either RISC (reduced instruction set computer) or CISC(complex instruction set computer).
