This library package provides several forward error correction (FEC) decoders and accelerated primitives useful in digital signal processing (DSP). Except for the Reed-Solomon codecs, these functions take full advantage of the MMX, SSE and SSE2 SIMD instruction sets on Intel/AMD IA-32 processors and the Altivec/VMX/Velocity Engine SIMD instruction set on the G4 and G5 PowerPC.
