Question
What is Microprocessor ?
Solution
(i) Microprocessor is a semiconductor, multipurpose, programmable logic device that reads binary instructions from a storage device called memory, accepts binary data as input and processes data according to the instructions and provides result as output.
(2) The electronic logic circuits in microprocessor are capable of performing various computing functions and making decisions to change the sequence of program execution.
(3) Microprocessor can also be viewed as an integrated circuit, that contains processing capabilities of large computers.
(4) A microprocessor can be roughly divided into three parts:
Microprocessor
1.Arithmatic and logic unit (ALU)
2. Registers
3. Control Unit
A.L.U is arithmetic and logic unit, where arithmetical and logical operations are carried out. Registers are primarily used to store data temporarily during execution of program. Control unit provides timing and control signals to the whole system. It also controls flow of data.
