Abstract: In order to achieve the right video image acquisition and multi-format output,images collected by  low-speed memory are usually used.This article describes the characteristics and application of  SAA7113 video decoder chip.Implementation of the SA7113 hardware circuit configuration structure is researched based on CPLD.Through  I2C bus,the VHDL language is used to initialize the control of programming.Therefore,video acquistion,image information collection by 8 MHz/s low-speed memory,and multi-format output can be achieved.

Key words: VHDL, SAA7113, I2C bus, CPLD
