Q4
If a CPU has a 4-stage pipeline that is divided into the following.
1. Fetch
2. Decode
3. Execute
4. Write back
If the CPU is going to execute the instruction \(\mathrm{a}=\mathrm{a}+10\), where a is a variable stored in the memory or cache. Describe the outcome generated by the various stages in the pipeline.
Note: you can define the processes being conducted at different stages of the pipeline.
