4
Consider a 5-stage pipeline with the following
features:
• The pipeline clock rate is 1 GHz
• For a non-pipelined implementation, ALU
operations and branches take 3 clock
cycles while memory operation will take 5
clock cycles.
• Relative frequencies of ALU operations,
branches, and memory operations are 50%,
30%, 20%.
• In the pipeline due to clock setup time, the
clock cycle time increases by 0.65ns.
Calculate the estimated speed up.
