论文摘要
本文研究了与HM-16.20相关的VTM-7.0的解码能量和解码时间需求。我们介绍了两个视频编解码器在软件解码器能耗方面进行的第一个详细比较。评估表明，与HM相比，VTM解码器的能量需求显着增加，并且增加取决于编码配置。对于随机编码配置，我们发现在解码时间增加70％以上的解码能量增加了80％以上。此外，结果表明，当禁用了多个数据（SIMD）指令时，能源需求将增加多达207％，这与HM实现样式相对应。通过测量结果，揭示了编码工具MIP，AMVR，TPM，LFNST和MTS提高解码器的能源效率。此外，我们根据分析提出了一种新的编码配置，该配置平均将VTM解码器的能源需求降低了17％以上。
This paper investigates the decoding energy and decoding time demand of VTM-7.0 in relation to HM-16.20. We present the first detailed comparison of two video codecs in terms of software decoder energy consumption. The evaluation shows that the energy demand of the VTM decoder is increased significantly compared to HM and that the increase depends on the coding configuration. For the coding configuration randomaccess, we find that the decoding energy is increased by over 80% at a decoding time increase of over 70%. Furthermore, results indicate that the energy demand increases by up to 207% when Single Instruction Multiple Data (SIMD) instructions are disabled, which corresponds to the HM implementation style. By measurements, it is revealed that the coding tools MIP, AMVR, TPM, LFNST, and MTS increase the energy efficiency of the decoder. Furthermore, we propose a new coding configuration based on our analysis, which reduces the energy demand of the VTM decoder by over 17% on average.
