Abstract :
This paper describes the audio system anddriver´s design of TLV320AIC23B under the operating system of WinCE5.0 based on AT91SAM9260. In the audio system SPI of AT91SAM9260 is used to configure AIC23, and SSC is used to transport audio data among them bidirectionally. The MDD/PDD Model is adopted in the audio driver. The main functions of PDD layer are implemented for MDD/PDD Model in the driver. More DMA buffers are allocated to improve the processing of audio data effectively in the driver. The driver can support recording and playing audio data at the same time, this driver performs well in real application.
