Doesn't SPICE use mostly floating-point for its simulations (I don't have a copy, so I don't know)?? If so, it's rather foolish to benchmark Integer M/D, with a floating-point package... I didn't chose the code, another poster did. As it happens, the circuit selected by the SPEC group causes SPICE to spend its time in a very different fashion than one usually expects (most of the commerical SPICEs have lavished great attention on fast solution of systems of equations (viz. linpack problem space stuff)) and that isn't true for this data set. Had it been true, the speed differential would be much more favorable for SPARC. -- Keith H.
