MULTI-CHANNEL SPEECH PROCESSOR WITH INCREASED CHANNEL DENSITY

摘要

An exemplary multi-channel speech processor (208) comprises a controller (220) capable of interfacing with a plurality of channels, and at least one signal processing unit (SPU) (222) coupled to the controller (220), wherein the multi-channel speech processor has maximum execution time for processing all frames, one channel (224) at a time, by processing a single frame from each of the plurality of channels. The signal processing unit encodes each of the single frames from each of the plurality of channels, one channel at a time, to generate encoded frames until (234a-234n) the maximum execution time elapses or is about to elapse. The controller (220) also transmits a pre-determined frame for each of the plurality of channels not processed during the encoding step, due to the maximum execution time elapsing or being about to elapse, such that the predetermined frame causes a decoder which receives the predetermined frame to generate a frame erase frame.
