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

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. 0:00 Introduction 0:36 Discussion 2:16 Get the scope out! 3:39 ALU Inputs 9:03 ALU Output 11:42 Flags 14:28 Pipeline 17:28 Fetch 23:03 Conclusions 24:58 The Critical Path 27:18 Outro
