Aiming at industrial on line image capture and transmission,a capture card is designed with gigabit ethen-et transimission function. The capture card is composed with DSP and FPGA,implementing image capture with cam-eralink interface and image preprocessing. The capture card recording products information with control signal send by Photoelectric isolation device. The development of the hardware circuit design about DSP and gigabit PHY inter-face in RGMII mode,and the procedure of DSP ethenet driver design are disscussed. When data is transmitted at full wire rate,sending diffrient packages,testing CPU load and transimiting rate. The conclusion indicates that the capture card has efficient,and independent,coincidenting real-time industrial on line capture and transmission re-quirement.
