Only way we could think of was to get bigger silicon or reduce the number of windows. .... At the IEEE HOT CHIPS forum, LSI/Metaflow presented a paper on a superscalar SPARC with (if memory serves) 4 functional units and at least 7 register windows. Even more interesting is its out of order execution model... -- ---------------------------------------------------------------- Keith H.
