Concept explainers
Central Processing Unit (CPU):
CPU is a part of computer hardware which has computer instructions to perform every operation in a system.
Explanation of Solution
Function of a CPU:
The functions of a CPU is categorized into four ways. They are:
- Fetch the instructions.
- Decode and interpret the instructions.
- Fetch and process the data
- Write the data
Fetch the instructions:
Every instruction in CPU has stored in memory with its own address. The processor fetch the address and track the instruction for operation.
Decode and interpret the instructions:
The computer programs should be translated into assembly language for its execution. So, the processor should decode the given program into binary instruction to execute the program.
Fetch and process the data:
Executing the instruction is another function in CPU processing. This function has three ways. They are: calculation with ALU, moving data from one to another memory location, and jump to different address.
Write the data:
The output data from all process written into the memory of the CPU.
