Mobile devices such as PDAs and cellular phones became indispensible part of business and entertainment world. There are a number of applications run on these devices and they tend to increase day by day causing devices tend to consume more battery power. H.264/AVC is an emerging video compression standard that is likely to be used widely in multimedia environments. As a mobile application, video compression algorithm of H.264 standard has a complex structure that increase the power demand of realizing hardware. In order to reduce this power demand, power consuming parts of the algorithm like deblocking filter and transform&amp / quantization need to be specifically changed for low power application. A low power deblocking filter and inverse transform/quantization algorithm for H.264/AVC decoder is to be proposed and implemented on FPGA.
