Abstract:
Based on the requirement s of high-speed dig ital video processing system centered about TMS320C6201, an analog video input interface to TMS320C6201 is designed w hich is composed of a hig h-speed Analog Font End( AFE) of video and an I2C bus microprocessor. The principle of the above design is analyzed, and several important problems associated w ith the system programming are discussed. Applicat ions indicated that this circuit is simple, high-eff-i cient , intelligent and less noisy , providing a clean data source for the next digital video f iltering .
