%description
MMIX is a computer intended to illustrate machine-level aspects of
programming. In the books The Art of Computer Programming, it replaces
MIX, the 1960s-style machine that formerly played such a role.  MMIX was
designed so that its machine language would be simple, elegant, and easy
to learn. At the same time it includes all of the complexities needed to
achieve high performance in practice, so that MMIX could in principle be
built and even perhaps be competitive with some of the fastest
general-purpose computers in the marketplace.
