Application Camera Links on Xilinx FPGA

In order to solve the problem that Camera Link standard interface used by the current industrial camera and image acquisition card could be realized only by making use of special integrated circuit, field programmable gate array (FPGA ) of Virtex5 series-the latest product of Xilinx was used, and at the same time very high speed integrated circuits hardware description language (VHDL) programming was used to realize logical sequence and signal control circuit of the Channel Link deserializer and the Frame Grabber on the Camera Link. Based on the bit error rate test and the integrity test of signal acquisition on at Camera Link, it was verified that the principle of system design was correct and acquiring normal image in the condition of high bit error rate was reliable. Thus, after applying designs of this system, resource transplantation was processed more effectively among the same series of FPGA, the hardware circuit was simplified, the development time was saved by more than 50%, and integration of the system was improved by 75%.
