But note that for the expense of the For quite a while, I have heard superscalar used, and I think the term was defined in a paper in IEEE Computer a while back, but I am still a little fuzzy on it. Is "superscalar" an exact concept, or is it a buzzword like "RISC"? Is a Multiflw machine a superscalar machine, or the i860, or the Weitek XL-8064?
