Image acquisition and VGA display system based on FPGA

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.
