Pentium 3D Library
In July-August 1996 I studied Intel’s Pentium processor, then programmed a 3D graphic library for a french company called Fatal Design. Nothing special to say about it, except that I learnt everything I could about caches, branching prediction, AGI, pairing, FPU coding, FPU tricks, SIMD, MMX, and so on.
Parts of this library were later used in various PC demos. This is all really obsolete nowadays.
