Abstract :
The rapid progress of computers and today´s heterogeneous computing environment means computation-intensive signal processing algorithms must be optimized for performance in a machine dependent fashion. We present formal machine-dependent optimizations of scalar and vector quantizer encoders. Using a dynamic memory model, the optimal computation-memory tradeoff is exploited to minimize the encoding time. Experiments show marked improvements over existing techniques
