Abstract: H.265 coding is known as HIGH efficiency video coding (HEVC). This is most successful video compression standard and extended from H.264/MPEG-4 advanced video coding (AVC) for same level of video quality. However, H.265 improved better video quality for same bit rate. In video coding, motion estimation (ME) is determined the motion vector from adjacent frames. Various algorithms have been introduced by many researchers to accomplish low power oriented ME. However, low power oriented full search block based motion estimation (LP-FSBME) algorithm gives accurate results. Architecture of sum of absolute difference (SAD) is used an adder tree to accumulate the processing elements. Power efficient 16:2 adder compressors in SAD architecture reduce the power dissipation rather than convention adders in SAD architecture. The hardware implementation of proposed method is done in Xilinx Virtex 7 FPGA XC7VX1140T device with speed grade 1 in Xilinx software version 14.5 tool, developed in Verilog Hardware Description Language (Verilog-HDL), and simulated in ISE simulator for tennis, BQ terrace and Kimono videos with the resolution of 1080×720 pixels with 30fps.
