HEVC Decoder Analysis on ARM Processor

摘要

In this paper, we perform an implementation of the High Efficiency Video Coding (HEVC) decoder on ARM processor. The complexity of HM10.0 reference software decoder has been profiled, using GNU gprof under the embedded Linux. In order to give indication of the most complex modules, numerous sequences were tested, for different resolutions and with two different Quantization Parameter (QP) values. This paper reveals the bottlenecks of HM decoder and provides implementation guidelines for future real-time HEVC decoder.
