Does anyone know of sites that post circuits for extremely simple
processors. Or any that have studied the minimum needed for processing.
I have a CPU with just one ALU instruction (logic NAND) from which I can
build up subroutines for every operation (all logic and mathematical
operations).
But i am wondering about what is the minimum number of
instructions/registers for the CPU setup that could still result in being
able to process? I have got it down to 4 registers and 6 instructions, but
im being pretty conventional about my setup (index pointer, instruction
pointer, two working registers). Wonder if you can get away with just 2
registers by smart sequences of instructrions?
