Is the VLIW more like microcode, controlling ALU's, gates and registers? VLIW is like a super scalar processor with the scheduling exposed to the compiler; IOW, there are many execution units and these are exposed to the compiler with a Very Long Instruction Width. The problem with VLIW has been (is?) that writing compilers to such an architecture has been very difficult and IMO that successive generations of chips which have different number of EUs ran old code very inefficiently. EPIC (HP/Intel VLIW) claims to fix these problems. How well, we'll see in the future. Muzo
