ALU (12: Logic) - Making an 8 Bit pipelined CPU - Part 43

This is the second of the big integration videos where I add the control decoding to the ALU and build the related instructions into the pipeline. In this video we handle all the bitwise logic operations (AND, OR, XOR and NOT) as well as the "clear carry" instruction and some compares.

I did hit one issue in this video, there is an anomalous load that confused me for a few minutes although it wasn't affecting the execution of the instructions. This turned out to be an issue that occurred to me when I had bigger problems a few videos back. Since it wasn't affecting the functionality that I was implementing / testing I moved on. I'll explain it in more depth in a future video. ... https://www.youtube.com/watch?v=aZWg_vQrxa8
