摘要： An audio codec control technique is provided with improved multichannel data ordering capabilities. An audio codec controller comprises a first interface unit for performing data transfer to and from an audio codec, a second interface unit for performing data transfer from an external memory, and a data buffer for buffering data received from the external memory via the second interface unit. The controller further comprises a capture register for receiving from the data buffer data requested by the audio codec, and temporarily storing the received data. The first interface unit is connected to receive temporarily stored data from the capture register. The operation of the audio codec controller may be done in several operational modes including 2, 4, and 6-channel full-rate and half-rate modes.
