Design of Audio and Video Collection Module Based on DM6467T

Aiming at the application of high-integrated DaVinci digital media processor, this paper proposes a high performance design method of embedded audio and video collection module. The module uses TMS320DM6467T as the core processing unit, and combines image coding and decoding chips including TVP5150, SII9125, ADV7342 to realize multi video I/O, and it realizes the functions of health management through monitoring voltage, current, temperature and BIT. The module design complies with 3U CPCI standard and it has rich function interface, is easy to reinforce. Experiment proves that the module can meet the high performance, high reliability and high safety application requirements of terminal equipment for vehicle mobile environment.
