Ask HN: Can You Build a CPU?
- PaulHoule 6y agoIt can be done: https://www.evilmadscientist.com/2016/6502/ https://www.evilmadscientist.com/2016/6502/ is a minicomputer implementation of the 6502. You can also make a "soft core" than can be uploaded to an FPGA, see https://en.wikipedia.org/wiki/Soft_microprocessor https://en.wikipedia.org/wiki/Soft_microprocessor Some of those are open source. Probably the simplest CPU architecture for the CPU hacker is https://en.wikipedia.org/wiki/Transport_triggered_architecture https://en.wikipedia.org/wiki/Transport_triggered_architectu... which is not only easy to design, but lets you add custom processing units such that you can codesign the chip with the software it runs.
