…mostly just doing the kind of logic minimization exercises you'd normally delegate to yosys. In https://github.com/kragen/calculusvaporis I designed a CPU instruction set, wrote a simulator for it, wrote and tested some simple programs,…

…kinds of somewhat unpredictable optimizations. Some kind of Forth machine, like Calculus Vaporis https://github.com/kragen/calculusvaporis , is one possibility. Another would be a simple register machine, something like the PIC; also in…

…conditional or unconditional, because it's reading the instruction stream from standard input. https://github.com/kragen/calculusvaporis/blob/master/cavosi... is a CPU simulator in 70 lines of code, but it's perhaps a bit impractical; you…

…code instead of JS, but I haven't gotten around to it. I also designed a minimal CPU architecture: https://github.com/kragen/calculusvaporis but I only have software implementations for it so far, and no interesting code. And I wrote a…

…are some thoughts about possible low-tech digital logic techniques. https://github.com/kragen/calculusvaporis has some thoughts about how to build a reasonably practical non-bit-serial CPU out of only about 1000 NAND gates (or
