This question is about pipelining. Compare the maximum clock frequencies for the three processors: P54C (5 pipeline stages), Pentium 4 Core 2 (14 pipeline stages), and Pentium 4 660 (32 pipeline stages). Assume the following:

All based on the same 65nm technology; (Base on same mother broad, same technical)

Fetch and execution sequence can be divided into steps of equal delay;

Work performed by each of the three processors is identical;

Propagation delay for the fetch and execution sequence is 3.9ns; and

Propagation delay of the register tR is 0.12ns.
