Mentioned elsewhere but I thought it might be worth a mention here. It's 6502-like but with just 40 instructions, no subroutines or interrupts, separate data and program, and 16 bit wide instruction bus for (mostly) single-cycle operation. Oh and just 8 bit addressing for instructions and again for data. Empirically it runs at 100MHz and is small enough to have many of them working in parallel, but timing analysis stubbornly says it won't run at that speed.
That is about 4-16 times faster than a full 6502 core on this FPGA
