What are the important differences between basic MIPS processor architecture and the one with pipelined implementation?
Homework Answers
A pipelined processor allows multiple instructions to execute at
once, and each instruction uses a different functional unit in the
datapath.
- This increases throughput, so programs can run faster.
- One instruction can finish executing on every clock cycle, and simpler stages also lead to shorter cycle times.

A non-pipelined processor has a clock rate of 1 GHz and an average instruction takes 9 cycles to execute. The manufacturer has decided to design a pipelined version of this processor. For this purpose, the instruction cycle has been divided into five stages with the following latencies: Stage 1 – 2.0 ns,Stage 2 – 1.5 ns, Stage 3 – 1.0 ns, Stage 4 – 2.6 ns, Stage 5 – 1.9 ns. Each stage will require an extra 0.4 ns for...
