Finding the Critical Path - Making an 8 Bit pipelined CPU - Part 101CritPath

In this video I analyse the cpu and attempt to identify the critical path through the circuit which constrains the clock rate. This was a thoroughly interesting experience which uncovered a few unexpected things but mostly confirmed the circuits workings.
