Abstract: A buffer controller includes a first write pointer generation module for generating a first write pointer that points to a first sequence of write locations in a buffer memory, that directs an input module to store a sequence of samples of a real-time signal in a buffer memory. A read pointer generation module generates a plurality of read pointers for a corresponding plurality of output modules, wherein each of the plurality of read pointers points to a sequence of read locations in the buffer memory, in a buffer order, that contain the sequence of samples.

Abstract: An integrated circuit and method of operation used in an audio playback device includes a host interface, a processing module, a multimedia module, a memory, and a filter co-processor. The processing module operably couples to the host interface and the multimedia module operably couples to the processing module. The memory operably couples to the processing module and to the multimedia module in which digital audio information is stored. The filter co-processor operably couples to the processing module and to the memory, wherein at the direction of the processing module the filter co-processor retrieves digital audio information from the memory and filters the digital audio information. In a playback mode, the filter co-processor retrieves the digital audio information from the memory, filters the digital audio information to produce filtered digital audio information, and writes the filtered digital audio information to the memory.
