by Olivier Henley – Feb 10, 2025. The Neorv32 BIOS project demonstrates how Ada can serve as a powerful alternative to C in open-source embedded development. Using a fully open-source stack—including Neorv32 (a VHDL-based RISC-V softcore), the ULX3S FPGA board, and an open FPGA toolchain—this…

Success! I rewrote a good chunk of my 8 bit RISC CPU (registers, stacks). Now that the ISA has been stable for a good while it's finally time to optimise the first implementation a bit. I shaved off 10 control signals in the process and saved quite a bit of area. It was already smaller than common 6502 and Z80 implementations, but is now even smaller.
Not that area was ever really a priority as such, but it's satisfying it's working out in the end.
