本研究提出了一种可编程和可配置的运动估计(ME)处理器,能够跨几种最先进的视频编解码器执行ME,这些编解码器包括多种工具,以提高计算运动矢量的准确性。核心可以使用优化的c风格语法进行编程,以实现任意块匹配算法,并根据所选择的编解码器、可用的内部编码选项和所需的性能配置不同的执行单元。这种灵活性意味着核心可以在高清分辨率和帧率下支持最新的视频编解码器,如H.264, VC-1和AVS。配置和编程阶段由集成开发环境支持,该环境包括编译器和分析工具,使没有特定硬件知识的设计人员能够针对所选编解码器标准和运动搜索技术优化微架构,从而实现高效的实现。
This study presents a programmable and configurable motion estimation (ME) processor capable of performing ME across several state-of-the-art video codecs that include multiple tools to improve the accuracy of the calculated motion vectors. The core can be programmed using a C-style syntax optimised to implement arbitrary block matching algorithms and configured with different execution units depending on the selected codec, the available inter-coding options and required performance. This flexibility means that the core can support the latest video codecs such as H.264, VC-1 and AVS at high-definition resolutions and frame rates. The configuration and programming phases are supported by an integrated development environment that includes a compiler and profiling tools enabling a designer without specific hardware knowledge to optimise the microarchitecture for the selected codec standard and motion search technique leading to a highly efficient implementation.
