Maybe you should take a look at this: http://home.comcast.net/~tom_forsyth/larrabee/larrabee.html http://home.comcast.net/~tom_forsyth/larrabee/larrabee.html "Rasterization on Larrabee and SIMD Programming With Larrabee: Michael Abrash and I doing our double-act. We both talk about the instruction sets, Michael talks about the hierarchical descent rasterisation algorithm, and I talk about how we do basic language structures such as conditionals and flow control with our 16-wide vector units. We were both absurdly proud to be able to finally talk about the architecture we'd worked on for so long - it's not every programmer that gets to design their own instruction set."
