Abstract
newline In the past few decades, there is a drastic improvement in the communication due to
newlineadvanced technologies and algorithms to make channel or media error free without
newlinecongestion. In this era, the bandwidth is limited for the transmission of data particularly biosignals
newlineand video signals through wired/wireless channels/media. The oldest communications
newlinewere lagging from transmission of video signals which require higher bandwidth. To address
newlinethese challenges, the proposed research work mainly concentrates on high efficiency video
newlinecoding (HEVC) and it is latest video coding standard to meet challenges in the digital
newlinemultimedia communication world.
newlineThe current video standards suffer from compression of data to reduce the bandwidth
newlinedue to lengthy computation techniques. Video codec needs to improve the compression speed
newlinewithout deteriorating the performance parameters like video quality, PSNR and structural
newlinesimilarity. The next challenge, in this research work is to address the limitations of DSP
newlineprocessor. This research work is to suggest the improvement in the computation speed by
newlineproposing suitable modifications in the existing DSP processor, the same is designed and
newlineimplemented on FPGA by utilizing the vedic algorithms, multi-stage pipelined structure to
newlineimprove the speed with optimized area and power dissipation. Further the work proposed a
newlinevideo codec (Application specific DSP processor) i.e. HEVC/H.265, a modified version of
newlineh.264 which performs better with respect to the all parameters. Xilinx 14.7 ISE and Vivado/
newlinechip scope-pro tools are used to test the efficiency of the proposed modification and
newlinealgorithms
newlineThe first phase of this research work, mainly concentrates on 64- bit DSP processor
newlinedesign by incorporating optimized advanced operation like error correction algorithm called
newlinebit wise error correction per symbol (BWECPS), floating point multipliers (as per IEEE 754
newlineformat), ALU, convolution, Encoder and decoder algorithm and advanced adder. The
newlinecomplete 64 bit DSP processor has been designed
