A methodology for implementing DSP applications on Field programmable gate arrays employing Xilinx System Generator (XSG) is presented. This paper outlines efficient hardware architecture for detection of exudates in retinal images. The proposed design comprises architecture for Sobel and Prewitt edge detection algorithms. The edge-map image obtained is enhanced for its perception using contrast stretching. Further, the image is segmented to detect the exudates. This design has been implemented on Virtex-II pro (XC2VP30-7FF896 platform). The code is synthesized within ISE 9.2 development suite.
