Question: Suppose a CPU that implements four parallel fetch-execute pipelines for superscalar processing.

Show the performance improvement over scalar pipeline processing and no-pipeline processing, assuming an instruction cycle similar to figure 4.1 in the commentary, i.e.:

- a one clock cycle fetch

- a one clock cycle decode

- a two clock cycle execute

and a 60 instruction sequence:

No pipelining would require __?__ clock cycles:

A scalar pipeline would require __?__ clock cycles:

A superscalar pipeline with four parallel units would require __?___ clock cycles:
