Very Long Instruction Word
VLIW

    (VLIW) Used to describe a machine
   code 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.
