What is the organization of CPU ?

1 Answer

Answer :

The central processing unit consists of three parts. These parts are: Arithmatic and Logic Unit Control Unit Register Memory Control Unit The unit through which all the functions of the computer are controlled is called control unit. It is a part of the computer's microprocessor that controls different parts of the computer. The function of the control unit is to control the continuity of the instructions received through the input devices, i.e. the instructions to be followed after the instructions. Controls when the flow of information will be in which direction. এসব Controls which part of the memory cell the information will be stored (for later use). Controls the interaction between the main organizational components of the computer. থাক Perform mathematical functions through ALU . • Sends ALU 's work results to main memory. ফলাফল Sends the results stored in the main memory to the output unit.
