Very Long Instruction Word

(VLIW) Used to describe an assembly language instructionset implemented using horizontal microcode. A horizontally

encoded instruction word which encodes four or more operations

might be considered "very long".

VLIW architectures are sometimes classified as a type of

static superscalar architecture. They are static in the

sense that which units operate in parallel is determined by

the instruction rather than by dynamic scheduling at run time.

Producing code for VLIW machines is difficult; tracescheduling is a helpful compiler technique.

The most famous VLIW machine was built by (the late)

Multiflow Computer, Inc.
