Abstract :
This paper introduced a scheme of design an embedded digital voice recording system on SOPC technology. By configure NiosII soft core CPU and some corresponding interface modules on a PFGA to construct an embedded system´ s hardware, and combine software programming to controlling audio encode and decode IC WM8731 and SDRAM system has realized A/D, D/A conversion, saving and replaying of audio signal. Due to using the SOPC and DMA technology, the system has high design flexibility and good expansibility and quick data processing speed.
