Design of Video Control System Based on USB Controller TUSB3210

This paper describes a design of video control system based on Texas Instruments's USB controller TUSB3210. According to the TUSB3210, the system realizes the initialization of registers of the PAL/NTSC decoder SAA7113H and the PAL/NTSC encoder SAA7121H through the IIC-bus, and realizes the program in system for the full system. As the video-part of the embedded system development based on the Nexperia PNX1500 multimedia platform, this design has been used in the platform and the performance has been proved well in large numbers of tests.
