Abstract :
Analog video data grabber system based on TMS320VC33 and SAA7111A is proposed for a kind of automatic optical alignment measuring device. System uses the enhanced video processing chip SAA7111A to complete A/D conversion. The function of SAA7111A and the register configuration method of I2C Bus are introduced in the paper. System uses FPGA to control video data grabber and collaborative work of DSP. DSP processes video data. The paper gives design method of hardware and software. Experimental results indicate that the system can satisfy the requirements.
