- Abstract
- This paper implements SIMD mechanism on ARM-based mobile processor for HEVC Decoders. The experimental results evaluating the performance of HEVC Decoders with/without SIMD are presented. In summary, the decoding rate with SIMD is 4∼5 times higher than decoding rate without SIMD. The results are up to 28 frames/s on multi-core ARM64 architecture with full HD video. The experiments also show the decoding performance comparison between the well-known open-source HEVC decodes such as Libde265 and openHEVCDecoder. In general, Libde265 achieved better decoding speedup than openHEVCDecoder in case of tile-based parallel processing. But it was less efficient in case of single threaded decoding because of the thread allocation on asymmetric multi-core processors. All experiments are conducted on Samsung Galaxy S6 with arm 64-bit architecture. © 2017 IEEE.
