Abstract: Concerning the drawbacks of traditional PCI frame grabber, using Altera's DE2 development platform, image acquisition and VGA display system of programmable logic chip based on Field-Programmable Gate Array (FPGA) were designed. This system used the programmable logic chip FPGA which was in-built into soft-core NiosⅡ as the controller. The FPGA has image sensor, digital memory, video D/A converter and VGA display interface as its accessories. System used System On a Programmable Chip (SOPC) technology to obtain control and coding over FPGA and its accessories and eventually to acquire, process and display the real-time images. The design results prove that, the electronic system based on SOPC technique is flexible and efficient in terms of designing, ported strong, easy to achieve high-speed data acquisition, and it has high compatibility.
