goddog said: or they could be streaming using the velocity engine (which each core on the cpu has 2 of ) to help. it can accelerate predetermined graphics function significantly if you put the work into it, especial polygon creation. but you must code like hell for it. edit ill post more when i get back im already way to far bebhind today
but i will not using velocity engine is something I dont think either party has done sony/MS yet so that would be interesting, also of note nintendo had thet technology though a diffrent version removed from its chip |
"Velocity engine" is just the name Apple gave to the SIMD instruction set commonly called AltiVec and used on modern PowerPC architectures. Actually both the Xenon and the Cell use it from launch, and that's why both have insanely high floating point performance compared to the x86-64 design used by AMD and Intel.
Plus the X360 CPU is not completely AltiVec-enabled. "as a number of integer operations were removed to make space for the larger register file and additional application-specific operations".
