For Following Functions:

M = (A.B.C) + (D.E.F) + (W.U.V) + (X.Y.Z)
a) Implement using single stage pipelining (output register), calculate latency, throughput and critical time.
b) What is the best throughput that can be achieved using two stage pipelining?
Show on your diagram.
Implement using 2-input AND gates of delay 4ns and 2-input OR gates of delay 2ns.
