AMD's 3DNow!/sup TM/ vectorization for signal processing applications
Dongho Kim, Gwangwoo Choe · 1999
AMD's 3DNow!/sup TM/ technology provides substantial speedup for digital signal processing applications. A set of DSP routines is vectorized with the 3DNow!/sup TM/ technology. The simplicity of the vector unit makes it easier to convert the conventional DSP programs into vector operations, and thus reduces the learning curve. The performance gain from typical DSP routines such as FIR, IIR and FFT indicates that the speedup can reach up to 1.5 compared to the conventional host-based signal processing units. 3D games and multimedia applications benefit from the technology. The vectorization can be integrated into compilers for the ease of use in increasing the performance of the signal processing applications.
