@Shufei @neauoire To get more exotic you could maybe have a big FPGA and dynamically program CPUs with arbitrary architectures to appear as needed. At times when you don't need much compute it could scale back to something very minimal and so conserve energy and reduce complexity, so higher reliability.
@Shufei 0_0 I don't know, I actually don't understand your question, it's too technical. I understand 6502 assembly, but I don't know anything about the electronics side aspect of it at the moment. Sorry :(
@Shufei @neauoire I seem to recall that the 6502 crashes if you stop it's clock (or run it too slowly), which might cause problems with this. I think maybe you'd need to feed the "idle" 6502s a synthetic stream of NOPs to keep them happy. In contrast, the Z80 is perfectly happy with arbitrarily slow clocking. You can even clock them by hand at sub-Hertz speeds with a switch! I found this very useful when building Z80 machines, you can stick LEDs on the pins and run the whole thing slowly enough to watch exactly what's happening on the buses, step by step.
