Abstract :
A new control technique of CPLD is presented. The new method successful initializes the video processor SAA7111. And the key technologies such as the structure of SAA7111, the communication protocol and realization are discussed in detail, together with the partial key procedure provided. The procedure is run in QUARTERS II,compiled ,debugged and simulated,the conclusion is that the procedure meets designing requirements. The design makes use of CPLD to analog for two transmission lines of I2C , completes control of enhanced video microprocessor SAA7111 through I2C bus.The method is more simple, flexible, lower resource occupied and portability compared with traditional CPLD way.
