...s > 1.0)? Otherwise, how can it be a useful value? Yes, it's a constant register. Because the instruction cannot contain an immediate value, a constant value may be stored in a constant register, and it's defined _before_ the program starts by API. For example: SetConstantValue( 5, Vector4( 1, 2, 3, 4 ); // C5 = <1,2,3,4> HANDLE handle = LoadCodeFromFile( filename ); SetCode( handle ); // C5 is referenced here Execute(); -- Tzu-Chien Chiu, 3D Graphics Hardware Enginner, <URL:http://www.csie.nctu.edu.tw/~jwchiu>

...of my code, or are there specific libraries that I should call? What I want to learn about is as simple as it gets: typedef double Double; // or whatever SSE* needs as close equivalent Double vector1[N], vector2[N]; // then fill them with stuff. vector3= vector_mult(vector1,vector2, N); vector4= sum(vector1, N); I just need a pointer and/or primer. PS: If someone knows of a superfast vectorized implementation of Gentleman's WLS algorithm, please point me to it, too. I am still using my old non-vectorized C routines. if this email offends as spam, apologies. regards, /iaw

All registers in my hardware are 4-element vector registers (128-bit). Some are floating point registers, and the others are integer registers. I typedef two packed classes: [4 x float] and [4 x int], and add an enum 'packed' to MVT::ValueType (ValuesTypes.h). I declared all 'RegisterClass'es to be 'packed' (first argument of RegisterClass): def GeneralPurposeRC :

Looking through the archives I have seen talk of making CPU specific optimisations for Vorbis, a la MMX/3DNow!/SSE. The feeling I gather is to wait until something is working well in C before committing to any kind of specific optimisation. What if oft used and needed DSP functions were identified and standardised DSP functionality be written for Vorbis? This would seperate the basically
