Abstract

This paper researches the scheme of design embedded high-speed image acquisition system on SOPC technology.The system realizes highspeed A/D,D/A conversion,saving and replay of image signal,by configureing NiosⅡ soft core CPU and some corresponding interface modules on a PFGA to construct the module' s hardware,and by combining software programming to controlling High-speed decode IC ADV7181 and encode IC ADV7123.Due to using the SOPC and DMA technology,the system has high design flexibility and quick data processing speed and good expansibility.
