Doing Boolean Algebra on My CPU – Superscalar 8-Bit CPU #34

The big missing piece of my 8 bit ALU is the ability to perform bitwise boolean logic operations. In this video, we are going to extend the ALU with a bit of circuitry that can perform any 2-input logic operation and replace the current XOR gates that conditionally invert the right-hand side for subtraction. By hooking this new circuitry up to the ALU operation decoder, we can define new AND, OR, and XOR operations, improve the existing NEG and NOT, and then use them in a new program. 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.
