Abstract

This paper presents an efficient architecture for various image filtering algorithms and tumor characterization 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 to hardware implementation. Performance of this architecture implemented in SPARTAN-3E Starter kit (XC3S500E-FG320) exceeds those of similar or greater resources architectures. The proposed architecture reduces the resources available on target device by 50%.

Highlights

The handling of digital images has become a subject of widespread interest in different areas such as medical, technological applications and many others
This objective lead to the use of Xilinx System Generator, a tool with a high- level graphical interface under the Matlab, Simulink based blocks which makes it very easy to handle with respect to other software for hardware description [10]
There are many research works related to image processing and its real time implementation using Xilinx System Generator (XSG) which uses high end hardware similar to the one used in paper [11] by Sami Hasan, Alex Yakovlev and Said Boussakta et al, complicated design used in paper [12] by Zhang Shanshan et al, but the proposed design in this work eliminates the design complexity, takes least resource usage and implemented in low cost basic FPGA device (Spartan 3E)

Summary

INTRODUCTION

The handling of digital images has become a subject of widespread interest in different areas such as medical, technological applications and many others. FPGAs are increasingly used in modern imaging applications image filtering[1,2], medical imaging[3,4], image compression[5,6,7], wireless communication[8,9].The drawback of most of the methods are that they use a high level language for coding. This objective lead to the use of Xilinx System Generator, a tool with a high- level graphical interface under the Matlab, Simulink based blocks which makes it very easy to handle with respect to other software for hardware description [10]. There are many research works related to image processing and its real time implementation using XSG which uses high end hardware similar to the one used in paper [11] by Sami Hasan, Alex Yakovlev and Said Boussakta et al, complicated design used in paper [12] by Zhang Shanshan et al, but the proposed design in this work eliminates the design complexity, takes least resource usage and implemented in low cost basic FPGA device (Spartan 3E)
