An efficient implementation of computing functions for Gauss mixtures using SIMD instructions of Pentium ®III and Pentium ®4 processors is described. The feasibility of OpenMP language for parallel computation of Gauss mixtures is studied.
The use of an optimized code in the speech recognition system allowed a reduction of inputs for probabilities computation from 80 to 30-45%. Optimized functions are included in the Intel Integrated Performance Primitives library.
