Expert Solution
Step 1: Describe the stages of an instruction pipeline in a CPU.
Modern microprocessor architecture relies on the instruction pipeline to optimize instruction execution efficiency and throughput. It divides instruction execution into phases that execute specialized duties. These synchronized phases let the CPU handle many instructions at once, improving performance. While CPU designs vary in the number of stages and their implementation, a typical pipeline has five stages: Fetch, Decode, Execute, Memory, and Writeback.
