I don't think "registers", as mentioned in that definition, and "registers" as exist on things like PICs match up very well. RISC usually involves memory/register move capability, with all the math and such happening between registers... PIC registers don't DO that... CISC, now; you haven't lived until you programmed a CPU that has machine level instructions directly supporting COBOL that execute somewhat more slowly than similar functions written (on the same CPU) in the more primitive primitives...
