The Itanium/Merced/McKinley line run the IA-64 instruction set. The IA-64
instruction set is actually 128 bits, not 64. Of the 128 bits, there are 3 sets of
40 bit operations and one 8 bit template to specify interdependence between
different words.

IA-64 is not true VLIW but a hybrid VLIW-Superscalar architecture. Over time
IA-64 and Sparc will converge architecturally as IA-64 adds more superscalar
profiling to compensate for compiler and real time deficiencies and Sparc adds
more CPUs on a single chip.
