Implementation of Image Processing Algorithms Using "Xilinx System Generator"

This paper presents an efficient architecture for various image enhancement and filtering algorithms using Xilinx System Generator (XSG). This architecture offers an alternative through a graphical user interface that combines MATLAB, Simulink and XSG and explores important aspects concerned for hardware implementation. The Xilinx System Generator tool is a new application in image processing, and offers a model based design for processing. The algorithms are designed by blocks and it even supports MATLAB codes through user customizable blocks. It also offers an ease of designing with GUI environment. This tool support software simulation, but most importantly it generates necessary files for implementation in all Xilinx FPGAs, with the parallelism, robust, speed and automatic area minimization. These features are essential in real time image processing. This paper aims at developing algorithmic models in MATLAB using Xilinx blockset for specific role then creating workspace in MATLAB to process image pixels and performing hardware implementation on FPGA.
