A microprocessor
A microprocessor, sometimes called a logic chip, is a computer processor on a microchip.
The microprocessor contains all, or most of, the central processing unit (CPU) functions and is the "engine" that goes into motion when you turn your computer on. A microprocessor is designed to perform arithmetic and logic operations that make use of small number-holding areas called registers. Typical microprocessor operations include adding, subtracting, comparing two numbers, and fetching numbers from one area to another. These operations are the result of a set of instructions that are part of the microprocessor design. Every microprocessor has a fixed set of instruction for its operation.
When your computer is turned on, the microprocessor gets the first instruction from the basic input/output system (BIOS) that comes with the computer as part of its memory. After that, either the BIOS, or the operating system that BIOS loads into computer memory, or an application progam is "driving" the microprocessor, giving it instructions to perform.
Controlling unit of a microcomputer, laid out on a tiny silicon chip and containing the logical elements for handling data, performing calculations, carrying out stored instructions, etc.
Function of microprocessor are :
It carries out the functions of the processor of an information technology system.
It contains a control unit (and clock), an arithmetic and logic unit, and the necessary registers and links to main store and to peripherals.
It can process programs, remember information, or perform calculations.
It also monitors, controls and executes the machine language instructions
Functions of microprocessor :
1) A microprocessor incorporates most or all of the functions of a central processing unit (CPU) on a single integrated circuit (IC)
2) A microprocessor is designed to perform arithmetic and logic operations that make use of small number-holding areas called registers.
3) Typical microprocessor operations include adding, subtracting, comparing two numbers, and fetching numbers from one area to another.
4) A microprocessor is the result of an electronics miniaturization technique and computer technology which provide programmable intelligence in a small package at relatively low cost.
5) They control the logic of PCs and almost all digital devices, from clock radios to fuel-injection systems in cars.
