7400 competition entry: Build your own FPGA

Posted on Tuesday, November 6th, 2012 in 7400 contest, contest by DP

Nick’s Open 7400 competition entry is an FPGA that is implemented in 7400 series discrete logic ICs:

Building a microcontroller or CPU out of discrete logic is a popular hobbyist pursuit, and it serves a useful purpose. Building a CPU from scratch teaches you a lot about CPU architecture and tradeoffs; it’s an interesting and instructive exercise. So, I wondered, wouldn’t building an FPGA out of discrete logic be similarly educational? Hence, my competition entry: an FPGA (or rather, a ‘slice’ of one) built entirely out of discrete logic chips.

Check out the video after the break.
