12/08/2009 Matrix inverse with SSE instructions

A while ago, I was speaking about my progress on GLM development using SSE instructions to optimized some code.

I published at DevMaster.net, the code source of a fast 4 by 4 matrix inverse and product.

The result seams really interesting to me: 162 CPU cycles instead of 918 CPU cycles on a Core 2 Q6600 for the inverse. 63 cycles instead of 378 CPU cycles for the matrix product.

A speed up by 5.66 times for the matrix inverse and by 6 times for the matrix product. Not bad?
