Edge detection is necessary tool for extraction of information for further image processing operation. Many computer vision application use edge detectors as primary operators before high level image processing. Several algorithms are available for edge detection which makes use of derivative approach. Roberts, Prewitt , sobel, canny are some of the examples of edge detection methods. In this project edge detection algorithms are to be implemented over FPGA board. Proposed architecture gives an alternative by using a graphical user interface which is developed by combining MATLAB, Simulink and XSG tool. Prototype of Application Specific Integrated Circuit ASIC can be obtained by FPGA based implementation of edge detection algorithm. Comparative analysis using software and hardware is to be done. Instead of using traditional approach of programming FPGA, Xilinx System Generator XSG is used for programming and modeling FPGA. XSG has an integrated design flow to move directly to the bit stream file from simulink design environment which is necessary for programming the FPGA. Advantage of using FPGA is power efficient circuits can be fabricated; it has large memory and superior parallel computing capacity. With use of FPGA, design procedure becomes more flexible.
