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...

We found that the instruction fetch and memory stages are the
critical path of our 5-stage pipelined MIPS CPU. Therefore, we
changed the IF and MEM stages to take two cycles
while increasing the clock rate. You can assume that the register
file is written at the falling edge of the clock.
Assume that no pipelining optimizations have been made, and that
branch comparisons are made by the ALU. Here’s how our pipeline
looks when executing two add instructions:
