摘要：A methodology for implementing DSP applications on Field programmable gate arrays employingXilinx System Generator (XSG) is presented. This paper outlines efficient hardware architecture for detection ofexudates in retinal images. The proposed design comprises architecture for Sobel and Prewitt edge detectionalgorithms. The egde map image obtained is enhanced for its perception using contrast stretching. Further the image issegmented to detect the exudates. This design has been implemented on Virtex-II Pro (xc2vp30-7ff896 platform). Thecode is synthesized within ISE 9.2 development suite. The results obtained via hardware software co-simulation uselimited FPGA resources at higher maximum frequency.
