基于异构多核处理器的H.264并行编码算法
H.264 Parallel Coding Algorithm Based on Heterogeneous Multi-core Processor
摘要
Abstract
H.264 video coding standard has high computing complexity, and is difficult to meet the high-definition video in real-time encoding. In order to solve this problem, this paper proposes a parallel coding algorithm on heterogeneous multi-core platform DM6467. By analyzing the dependence between different hardware accelerators and the characteristics of different levels of memory, a macroblock level parallel scheme is designed. Further optimization is carried out by merging the pipeline of adjacent slices and balancing the tasks assigned to Digital Signal Processor (DSP) and ARM cores. Experimental result shows that the efficiency is improved by 18%, and 1080P real-time H.264 video encoder can be realized on DM6467 platform.关键词
