If there are no branch mispredictions and no data dependences, what is the expected performance improvement over a 1-issue processor with the classical 5-stage pipeline? Assume that the clock cycle time decreases in proportion to the number of pipeline stages.

This exercise explores how branch prediction affects performance of a deeply pipelined multiple-issue processor. Problems in this exercise refer to a processor with the following number of pipeline stages and instructions issued per cycle:
