An Efficient SIMD Implementation of the H.265 Decoder for Mobile Architecture

摘要

This paper focuses on an efficient optimization of the H.265 video decoder on suitable architectures for mobile devices. The solutions developed to support the H.265 features, and the achieved performances are shown. The most demanding modules have been optimized with Single Instruction Multiple Data (SIMD) instructions and we keep in special account the memory handling, with the minimization of the memory transfer. The effectiveness of the proposed solutions has been demonstrated on ARM architecture. In particular, we have selected the dual-core Cortex A9 processor with NEON SIMD extension.
