Computer Science CPU Project

TTL RISC CPU Project – Building a Programmable Program Counter

The latest episode of our project to build a CPU is now online.  It’s likely to be the last for a couple of months because of the summer holidays (and my internship – more to follow on this shortly).  The series (‘Mum, I am Building a CPU’) has now passed 1500 video views, so that’s fantastic.

In this episode (embedded below), I talk about constructing a program counter with support for Jump instructions.  We built this over two bread boards, and I go through first the logic and diagrams, then the actual circuitry.
