This paper presents our high performance architecture for Motion Estimation (ME) using efficient 4-2 and 8-2 adder compressors to calculate the Quarter Sub-sampled Diamond Search (DS) block matching algorithm with Dynamic Iteration Control (QSDS-DIC) [1]. Motion estimation (ME) is the most important task in the current standards of video compression. Full(More)
This paper proposes a novel approximate computing algorithm for the Sum of Absolute Transformed Differences (SATD) to meet energy efficiency in CMOS accelerator circuits. It is based on the pruning of least significant coefficients in the 2-D Hadamard Transform (HT) which is the most compute intensive kernel in the SATD. The SATD is a metric for block(More)
