Very Long Instruction Word
(VLIW) Used to describe an assembly language instruction set 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; trace scheduling is a helpful
compiler technique.
The most famous VLIW machine was built by (the late) Multiflow Computer, Inc.
