Computer Architecture The Anatomy of Modern Processors
VLIW Processors
Very Long Instruction Word (VLIW) processors have
instruction words with fixed "slots" for instructions that map to the functional
units available. This makes the instruction issue unit much simpler, but places
an enormous burden on the compiler to allocate useful work to every slot of
every instruction.
