The purpose is to study the I2C bus,it has the interface cable and control simple devices are packaged in small,higher commu-nication speed,etc,so select the SAA7113 as video decoder chip. It gives a brief account of the data transmission timing of the I2C bus protocol,the basic functions of the analog video decoding chip SAA7113 works and associated register set,and presents a SAA7113 ini-tialization approach based on FPGA,overviews each module of the I2C bus in detail,and is given in the register configuration of the chip initialization state transition diagram,finally use the Quartus software for simulation,the experiments show that data transmission complies with the provisions of the I2C protocol. The results show that correctly configure the chip,and have video data collection.
