Remote Access of Peripherals Using Web Server on FPGA Platform

Remote controlling of devices or peripherals interfaced with an MCU is essential in couple of applications in Embedded Systems. Web Server is one of the best solutions to do such task if internet is available at such remote locations. The important aspect of this paper is to port an open source Embedded Linux operating system on the FPGA to manage the hardware resources. It is pre-emptible and can be used in place of RTOS. The foremost challenge in implementing this work is to ensure that the embedded IP cores must be visible to the operating system as well as to the user. A complete toolchain is developed on a Linux desktop machine and kernel image is cross compiled for the PowerPC processor. Important aspect addressed by this paper is to configure the Linux for Web Server application and to control LED device through any remote machine in the same network.
