Abstract:

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