Knuth's home page about MMIX says:

MMIX is a machine that operates primarily on 64-bit words. It has 256 general-purpose 64-bit registers that each can hold either fixed-point or floating-point numbers. Most instructions have the 4-byte form `OP X Y Z', where each of OP, X, Y, and Z is a single 8-bit byte. For example, if OP is the code for ADD the meaning is ``X=Y+Z; i.e., ``Set register X to the contents of register Y plus the contents of register Z. The 256 possible OP codes fall into a dozen or so easily remembered categories.
