A 5-Stage pipeline is composed
of the following stages Instruction Fetch (IF), Decode (DE),
Execute (EX), Memory Access (ME) and Register Write-back (WB).
Assume the pipeline does not have a branch prediction unit, does
not have superscalar support and does not support out of order
execution. Assume that all memory accesses are in the L1 cache and
therefore do not introduce any stalls. Show a pipeline diagram that
shows the execution of each stage for the assembly code below. Also...

Consider the following MIPS assembly language instructions: addi $1, $2, 100 swr $1, 0($2): addi $rt, $rs, immediate # add immediate swr $rt, immedi ate ($rs) # store word write register These instructions are I-format instructions similar to the load word and store word instructions. The addi and swr instructions store a computed value to the destina- tion register $rt. The instructions do not require any physical hardware changes to the datapath. The effect of each instruction is given below....

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:
