Simple CPU Instruction Set Design

It actually takes very little hardware to implement a CPU if you don't need high performance.  Today in class we built a CPU with the very basics:

There are a few key tricks used throughout these designs:

Here's the 24-bit instruction set CPU we built in class in 2016.

Here's an 8-bit instruction CPU we built in class in 2014.  A few more examples are listed at my 2012 CPU design page.
