Question: Consider a processor with a 4 - stage pipeline ( Fetch , Decode, Execute, Write - back ) . Each stage takes 1 0 nanoseconds

Consider a processor with a 4-stage pipeline (Fetch, Decode, Execute, Write-back). Each stage takes 10 nanoseconds
to complete. Assume the following without pipelining, a single instruction takes 40 nanoseconds to complete
(10 nanoseconds for each stage)
Calculate the total time to execute 100 instructions with and without pipelining.
Determine the speedup achieved using pipelining.
