Question

consider the unpipelined processor that has 1 ns clock cycle and that it uses 4 cycles for Alu operation and branches and 5 cycles for memory operation. Assume that the relative frequencies of these Operations are 40%, 20% and 40% , respectively. what is the average instruction execution time on this unpipelined processor?​

Answer 1

Answer:

Step-by-step explanation:

For pipelined processer

Execution time =1+0.15=1.15

For non-pipeline processer

Execution time = 4*50/100+5*35/100+4*15/100=4.35

Speed up= 4.35/1.15=3.78
