Abstract :
Effectiveness of MMX for digital signal processing on general-purpose processors (often referred to as Native Signal Processing) is evaluated. We benchmarked a variety of signal processing algorithms and obtained speedup (ratio of execution speeds) ranging from 1.0 to 4.0 by using MMX technology over non-MMX code. Efficient, reliable and standard C code is also evaluated with respect to NSP library assembly code from Intel
