- W1980792802 abstract "To achieve a target bit-rate reduction of 50% over H.264/AVC while maintaining equivalent perceptual video quality, High Efficiency Video Coding (HEVC) includes several new coding tools including a new set of integer transforms. Since these transforms are more complex than the H.264/AVC transforms, it is more challenging to design and develop high-performance integer transform hardware for HEVC. In this paper, we propose a series of high-throughput and low-cost hardware-oriented HEVC transform algorithms by using a butterfly structure and replacing multiplications by additions and shift operations in a way that minimizes critical computation paths. Compared to the algorithms using other methodologies like multiplierless multiple constant multiplication (MMCM) or decomposition to sparse matrices, our algorithms achieve around 20% shorter critical paths while consuming relatively small numbers of additions and shift operations. Hardware designs applying our proposed algorithms can increase their throughput by 20% while maintaining a reasonable resource consumption compared to when applying other algorithms." @default.
