摘　　要：当前,嵌入式设备已经深入人们生活的各个方面,但基于国产内核的SOC嵌入式设备尚处于起步阶段。SEP6200是由东南大学国家专用集成电路工程研究中心采用北大UNICORE内核架构自主设计研发的高性能SOC芯片,我们提出并设计了以SEP6200及CS3700芯片为硬件基础,详细介绍了ALSA及ASOC软件架构,并以此为基础设计了LINUX系统音频驱动。通过在平台上移植MPLAYER播放器,以实现放音及录音测试,实验表明该驱动系统在SEP6200平台上运行稳定,达到了预期效果。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.
