ABSTRACT
A VLIW (very long instruction word) processor is also designed for fetching, decoding, executing, and completing multiple operations each clock cycle. The difference between a superscalar processor and a VLIW processor is one of implementation and architecture. Superscalar design can be applied as an implementation technique to an existing sequential instruction set, while VLIW design requires that the instruction set architecture, the implementation, and the compilers be specifically designed to support the packaging of multiple independent operations into long instruction words.
