Abstract

With development of the coding theory and multimedia network application,the application of the image and video compression coding JPEG2000 system have been extended gradually.Proceeding with the characteristics and protocol of the I2C bus in the video acquisition,the design and realization method of I2C bus are introduced emphatically.Based on the video acquisition chip SAA7111,the method to simulate and realize the I2C bus interface by the did of VHDL language,and embed it into FPGA is proposed.The simulation results show that the data is correct stable and reliable.
