Title

Efficient Adder Compressor Design for Sum of Absolute Difference Calculation

Abstract

In video encoding Motion Estimation is the tech- nique used to exploit temporal redundancy of video sequences. The Motion vector defines the change of previous frame from its present frame of the video in the Block Matching Algorithm. An accurate method is required to calculate the motion vector. The Sum of Absolute Differences (SAD) is the best distortion metric used to obtain the best match in Integer Motion Estimation. SAD calculation is one of the most time consuming operations of video encoders. SAD architectures employ an adder tree to accumulate the coefficients from absolute difference between two video frames. The 8:2 adder compressors implemented using combination of 4:2 adder compressor is found to be better among all the architectures based on delay and power consumption. The SAD architecture using four different structures of adder compressors are simulated using Xilinx ISE. The system perfor- mances are evaluated by comparing the power dissipation, delay and area.

Key Words

Integer Motion Estimation (IME), Motion Vec- tor (MV), Sum of Absolute Difference (SAD), Block Matching Algorithm.
