Floating-point architectures (continued)
Scalar vs MLIW (visual instruction sets and Intel IA-64) vs vector (8 -- 256 elements)
Quadruple-precision (only IBM S/390’s hexadecimal and ANSI/IEEE 754 formats, and Hal SPARC64-GP, are in hardware; all others are in software, but IBM RS/6000 and SGI terribly brain damaged and buggy)
