ABSTRACT:
A method for storing and transferring wave table audio samples from system memory to a cache unit. The method creates a linked-list of pages in system memory for storing the audio sample. The linked-list is actually a pointer list indicating the locations in system memory where the audio samples are stored. A Digital Signal Processor (DSP) is able to translate the starting address of the pointer list to retrieve a requested audio sample from the system memory. The requested audio sample is then transferred to the cache unit where the DSP is able to retrieve audio samples in a linear fashion at a rate much faster than individually fetching the required portions of the audio sample from the main memory of the system.
