mmix for Mac

mmix is a suite of command-line tools built around the 64-bit RISC architecture designed by Donald Knuth, aimed primarily at readers learning computer architecture, instruction sets, and low-level programming. It addresses the question of how to understand how machine instructions work on a clear, well-specified, hands-on model—compared with real hardware, this teaching-oriented architecture is better suited to observing the relationships among registers, memory, and instruction execution. For students and teachers reading The Art of Computer Programming or taking related courses, as well as developers who want to understand RISC design at the assembly level, mmix provides an environment that can actually be run and experimented with, helping to ground abstract concepts in concrete operations.
