Abstract

An audio information processing subsystem 200 is disclosed which includes a stream processor 100 for simultaneously processing multiple streams of audio data. Processing subsystem 200 also includes a program memory 202 coupled to stream processor 100 for storing instructions for controlling processing system 200 and a data memory 203/204 also coupled to stream processor 100. Additionally, a direct memory access circuitry 208 is provided for controlling direct memory accesses to a selected one of program memory 202 and data memory 203/204.
