Just saw https://www.youtube.com/watch?v=2fi1fsKtfxc and I really like where this is heading. I can't wait to get my hands on the final hardware.
I wonder, will there be room left of the FPGA to play with? Is is feasible to tinker with the final version and, let's say, customize the cpu by adding a 8x8 -> 16 multiply instruction.
The prospect of being able to extend the system on the hardware level is fantastic and I hope this is considered to be a supported usecase.
