论文摘要
本文介绍了下一代多功能视频编码(VVC)的记忆评估。记忆分析是作为最先进的高效视频编码(HEVC)的基线进行的。目的是提供与HEVC相比,对VVC的记忆要求的严重关键的洞察力和观察。所采用的方法包括两组实验:(1)整体记忆分析和(2)预测间记忆分析。在内存分析中获得的结果表明,VVC访问比HEVC多13.4倍。此外,预测间模块仍然(如HEVC中)在编码器中是资源密集型操作:60%-90%的内存需求。预测间的特定分析表明,与HEVC相比,VVC需要多达5.3倍的内存访问。此外,我们的分析表明,这种增长的23%是由于VVC新颖CU尺寸(大于64x64)。
This paper presents a memory assessment of the next-generation Versatile Video Coding (VVC). The memory analyses are performed adopting as a baseline the state-of-the-art High-Efficiency Video Coding (HEVC). The goal is to offer insights and observations of how critical the memory requirements of VVC are aggravated, compared to HEVC. The adopted methodology consists of two sets of experiments: (1) an overall memory profiling and (2) an inter-prediction specific memory analysis. The results obtained in the memory profiling show that VVC access up to 13.4x more memory than HEVC. Moreover, the inter-prediction module remains (as in HEVC) the most resource-intensive operation in the encoder: 60%-90% of the memory requirements. The inter-prediction specific analysis demonstrates that VVC requires up to 5.3x more memory accesses than HEVC. Furthermore, our analysis indicates that up to 23% of such growth is due to VVC novel-CU sizes (larger than 64x64).
