In this paper, a design of CMOS image sensor interface controller based on FPGA is presented. The controller works as an interface between CMOS image sensors and other units for video surveillance. The top-down design method is adopted to partition and design each sub-module of the controller. This controller can perform the functions of acquiring, processing and storing information from image sensors. The asynchronous FIFOs, the three-way division unit and the embedded DMA are designed to improve the speed of data transmission and avoid the conflicts of data transmission on AHB. It is successfully implemented on the video surveillance system based on a FPGA board. The simulating and verification results show that the image can be captured and transmitted without distortion.
