The ideal speedup of a pipeline is equal to the number of stages in the pipeline. For example, splitting a 50 ns operation into 5 stages, each 10 ns long, will result in a 5x speedup. So, the ideal speedup of a pipelined system with four stages is four. This statement is true.

6(10%) (Pipelining) Suppose you have a system where every problem must pass through 4 pipeline stages with delays of 30ns, 60ns, 15ns, 20ns. Each stage cannot be replicated, but can be pipelined. (a) What is the minimum number of stages, from beginning to end,in a pipeline that has no load imbalance? (b) What is the clock cycle time for this case, assuming clock to q delay, setup time and hold time is 2ns for registers?
