We want to compare the latency and the cycle time of a pipelined and non-pipelined processor design. Assume that individual stages of the datapath have the following latencies:

IF

ID

EX

MEM

WB

250ps

350ps

150ps

300ps

200ps



a.  What is the clock cycle time in a pipelined and non-pipelined processor?
b.  What is ld instruction latency in a pipelined and non-pipelined processor?
c.  Assume 10 consecutive instructions are executed in the pipelined and the non-pipelined processors. What is the total execution time on the two processors? Note that there is no data or control dependences among the 10 instructions.
