Research and implementation of ASOC audio driver model on the Blackfin platform

摘要：

The development of Audio driver is very important in embed audio system, which decides the performance of audio system directly. WM8731 audio driver is implemented on uclinux embedded operating system by using ASOC driver model in this paper. And in the design, combining the characteristics of Blackfin561 and uclinux sufficiently. To achieve the demand of real time characteristic by using the techniques of interrupt, DMA and Circle buffer storage, the performance of system is enhanced. Audio driver procedure in this paper is proved steady and reliable after many tests.
