What does the abbreviation 'VLIW' stand for?

VLIW = "Very Large Indigo Waterbuffalo" Glad I could help. --- Sean

Don't forget KLIW - Kinda Long Instruction Word (really). Essentially, VLIW it refers to what used to be called Horizontal microcoding (the ability to execute in parallel autonomous functional units or "slices"). >

Well, I suppose that superpipelined or superscalar processors
are trying for high performance. But they don't have a KLIW.

My understanding of the two terms is slightly different. Horizontal micro-coding implies that you haven't encoded any of the control state. (As oppossed to pure-vertical which would mean that you've fully encoded your micro-word.) Your statement about VLIW really being several instructions in one word so that parallel operation of severl functional units can take place fits with my understanding of the term. The difference between the two is subtle and perhaps you might say that VLIW is a subset of Horizontal microcoding. The difference being in that I can have a completely horizontal microcode word that can only do one thing at a time(i.e. one functional unit). I've just chosen not to use decoding of the state in the implementation. Steve Wilson
