摘要
An audio bus interface system and method interfaces a plurality of digital signal processing devices to an audio bus to facilitate variable processing loading on the DSPs. The audio bus contains frames with synchronization data. The system utilizes a programmable interrupt controller for each digital signal processing unit. The programmable interrupt controller controls the rate at which a given DSP can be interrupted. The respective digital signal processor controls the programmable interrupt controller to maximize its throughput. Also, an audio format translator allows differing audio format protocols to be processed by the same audio DSP.
