Guess I was wrong!(?) Axel already cleared that up. If you'd like to learn more about CPUs, a good source is Ars Technicas Technopedia section "CPU Theory and Praxis" at <http://arstechnica.com/cpu/index.html>. They've got a nice introductory article about SIMD architectures, going into some detail on MMX, SSE, 3DNow! and PowerPCs AltiVec; this would be a good read for anybody interested in the possibilities of SIMD: <http://arstechnica.com/cpu/1q00/simd/simd-1.html> Bye, Chris
