DSP源码
DSP implements several low-level digital signal processing (DSP) primitives accelerated, when available, by the Intel/AMD SIMD instruction sets MMX/SSE/SSE2. Portable C versions are provided for compatibility on non-IA32 machines. Routines are provided to compute 16-bit integer dot products (FIR filtering, correlation); sum-of-squares (signal energy measurement), and peak sample detection (for automatic gain control, etc.).
DSP加快实现对几个低级的数字信号的原始处理，当可利用时，用Intel/AMD SIMD 说明MMX/SSE/SSE2装置。轻便的C译文，为non-IA32机器提供兼容性。日常被用来计算16bit整数的乘积（FIR过滤，相互关系）；平方和（单个能量的测量）和最高除法（为自动获得控制等等）。
