Study Notes
Fetch Execute Cycle
- Fetch involves retrieving an instruction from computer memory to run a program.
- Decoding breaks down the retrieved instruction into smaller parts that are dispersed throughout the CPU.
Execution
- The broken-down instructions are executed in various parts of the CPU to perform the desired operation.
Writeback
- The CPU outputs the results of the executed instructions in the writeback step.
