Abstract
Video Compression is very essential to meet the technological demands such as low power, less memory and fast transfer rate for different range of devices and for various multimedia applications. Video compression is primarily achieved by Motion Estimation (ME) process in any video encoder which contributes to significant compression gain. Sum of Absolute Difference (SAD) is used as distortion metric in ME process. In this paper, efficient Absolute Difference(AD)circuit is proposed which uses Brent Kung Adder(BKA) and a comparator based on modified 1’s complement principle and conditional sum adder scheme. Results shows that proposed architecture reduces delay by 15% and number of slice LUTs by 42% as compared to conventional architecture. Simulation and synthesis are done on Xilinx ISE 14.2 using Virtex 7 FPGA.
