Abstract :
An MPEG-2 audio decoding processor core is described with the main theme focused on inverse quantization (IQ) and multichannel processing (MC). By means of a novel architecture, the IQ achieves a high throughput, and MC performs different types of dematrixing modes employed by the standard MPEG-2 algorithm with a flexible data allocation. The processor core is implemented and controlled with a dedicated hardware approach instead of the traditional programmable techniques. Moreover, the design has the advantages of simplicity and low cost, satisfying the high efficient requirement with fixed throughput
