AVS video decoder on multicore systems: Optimizations and tradeoffs
(2011)Newer video compression standards provide high video quality and greater compression efficiency, compared to their predecessors. Their increased complexity can be outbalanced by leveraging all the levels of available ... -
A Fast Heuristic for Tile Partitioning and Processor Assignment in Hevc
(2018)As the compression efficiency of HEVC comes at the cost of high complexity, especially in the encoder's side, improved parallelization techniques that will speedup the encoding process are essential. One of the parallelization ... -
Mapping and optimization of the AVS video decoder on a high performance chip multiprocessor
(2010)Modern multimedia workloads provide increased levels of quality and compression efficiency at the expense of substantially increased computational complexity. It is important to leverage the off-the-shelf emerging multi-core ... -
On the Evaluation of Coarse Grained Parallelism in AV1 Video Coding
(2018)Video compression is arguably one of the most time consuming tasks, especially at high resolutions. For this reason parallelization has been used at various levels: from coarse grained schemes that consider groups of blocks ... -
Tile Based Wavefront Parallelism in HEVC
(2020)High Efficiency Video Coding (HEVC) was developed to tackle the 4K resolution era, achieving up to 50% more compression efficiency (for the same video quality) compared to its predecessor H.264/AVC. However, this performance ...
