Web Server and QR Decoder Applications for Xilinx FPGA Boards

Abstract

The microelectronic industry is undergoing dramatic changes nowadays. Every year faster and more advanced systems are released. They are capable of running more complex tasks than before for a fraction of a PCs price. The task of this paper is realization of two applications that run on an embedded system. The first one is a QR (Quick Response) image decoder and the second one is a web server. The requirement was for the QR decoder to decode a stream of images and for the web server to process certain HTTP requests. Most existing versions of these applications are designed to run on PCs. Since only a part of their functionalities were needed, the best solution was to develop the applications in C programming language and implement them on a system as bare-metal programs. With this approach the performance can be maximized and the development time of the software shortened.
