That is the start of the videos where the control logic gets microcoded. Its pretty basic but over the next few videos he comes up with about 10 different OPCODES and programs their microcode (a series of control logic activations). Its pretty amazing to see it all come together and work in the end.
- anyfoo 3y agoYes, absolutely. Ben Eater’s series is fantastic. If you want to learn about simple microcode and how a (non-superscalar, which matches the 8086) CPU generally works, this is a brilliant resource, and fun to watch.
- pests 3y agoHis entire channel is brilliant. I also love his homemade GPU. I forget sometimes just how fast CPUs are so watching him 'race the beam' (not literally anymore, but HDMI has timings just the same) is fascinating.
