Abstract

This paper introduces a design of digital audio playback embedded system based on FPGA.Using WM8731 encode and decode chip,configure NiosII soft core CPU and some corresponding interface modules on a FPGA to construct an embedded system's hardware,and combine software programming to controlling audio encode and decode chip and SD card,the system realized A/D,D/A conversion,saving and replaying of audio signal.Due to using the SOPC technology,it has high integration,good stability,design flexibility and high design efficiency.
