Register File Port PCB – Superscalar 8-Bit CPU #40

With the ALU finished it is finally time to move most of my homebrew CPU's breadboards onto dedicated PCBs. In this video we sketch out the first two backplanes of the CPU and plan which breadboards get turned into PCBs. We then design, layout, assemble, and test a first PCB for the register file ports.

This video series explores the concepts and techniques that make modern computer processors so incredibly fast and powerful. I build my very own 8-bit processor from individual logic gates and gradually evolve it to become a superscalar out-of-order machine. Along the way, we take a deep dive into contemporary computer architecture in a hands-on fashion and rediscover some of the foundations of modern computing.
