Why is the Intel(r) XScale(tm) Core Scalar?
The Intel(r) XScale(tm) core was designed to deliver high performance while providing good efficiency (MIPS/Watt). We think a good way to meet these goals is to use a scalar microarchitecture, rather than superscalar. This talk will present some rationale behind such thinking.
Mike Morrow has been a processor architect in the Intel(r) XScale(tm) Core design team since the first tape-out of this microarchitecture.
