VLIW

from The Free On-line Dictionary of Computing (8 July 2008)
Very Long Instruction Word
VLIW

   (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.}
