Design of a Linux Audio Driver Based on the SEP6200

Currently,embedded devices has penetrated every aspect of people's lives,but embedded devices based on domestic CPU core SOCs are still in their infancy. SEP6200 processor designed by Southeast University National ASIC Engineering Research Center is a self-developed high-performance SOC chip using Unicore core architecture of Peking University. This new Linux audio decoder driver has been proposed and designed,which is based on the hardware of SEP6200,CS3700 and software of ALSA,ASOC architecture. We port the MPlayer to the platform,in order to achieve sound and make recording test. Experiments show that the driver system runs on the platform of SEP6200 steadily and achieve the desired results.
