Finally finished my little CPU project, RISCY-V02. I built it (with Claude) to challenge the notion that the 6502 was a "local optimum" in its transistor budget. Given the constraints of 1970s home computers (~1 MHz DRAM, so raw clock speed doesn't help), could RISC have been a better design choice? This design argues yes: pipelining, barrel shifters, and more registers beat microcode PLAs, questionable addressing modes, and hardware BCD. Highlights: 8x 16-bit general-purpose registers (vs 3x 8-bit on 6502) 2-stage pipeline (Fetch/Execute) with speculative fetch 61 fixed 16-bit…

This is a personal project I've been working on and off for the past few years. It's a set of tools that have allowed me to prototype quickly small (and increasingly bigger) kernels, and create userspace programs to interact with them. Supports riscv64, amd64 and i386. The intel port has been tested and used on real hardware, from big dual-socket Xeon machines to an old X220. It is all C, I have plan to make rust bindings for the kernel library. But again, they're plans at this stage. Porting to new architectures is relatively simple, a basic port to riscv took me a couple of weeks of…
