Poor Man's Conditional Jump – Superscalar 8-Bit CPU #36

My homebrew CPU has recently gained four glorious arithmetic flags in its ALU. In this video, we are going to use these flags and the improved control over when registers are updated to define compare, test, and flag swap instructions. An updated assembler with support for these instructions will then allow us to write a fresh new program that puts the flags through their paces and even implements a poor man's conditional jump to compute a multiplication. 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.
