Question

Squidward has decided to branch out into hardware design. Being new to the field, he's asking for your help in designing a pipeline of a new processor. Once the processor has been built, he's going to test it with a sample program that contains 108 instructions.

Answer 1

Time taken by non pipelined is

No. of instructions x No. of stages x Time taken by a stage = 10⁸ x 14 x 70 = 980 x 10⁸ ps

Time taken by pipelined is

(14 x 70) + (10⁸ -1) x 70 = 980 + 699999930 = 700000910 ps

SpeedUp= Time Non Pipelined Time Pipelined 980 x 108 700000910 = 139.998 140

So pipelined processor is 140 faster than non pipelined processor
