  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.
