Performances analysis and evaluation of Xenomai with a H.264/AVC decoder

The expansion of the market for embedded systems has motivated academic research to offer solutions to the problems of congestion and connectivity. Indeed, the implementation of the embedded processor on FPGA helps saving space and provides a better interaction between the program and hardware acceleration. Furthermore, the addition of an Operating System (OS) allows to abstract the hardware and to control devices by software. In fact, all these parameters converge to use a Real-Time Operating System implemented in FPGA (in our case, FPGA Xilinx Virtex 5 ML507 board is used). The basic idea of this paper is to evaluate the performances of Xenomai running in the PowerPC processor, with the H.264/AVC video decoder.
