| 摘 要： | 视频解码芯片的结构因硬件强大的处理能力和软件灵活的可编程功能从硬件转向软硬件分区结构。该文针对AVS标准的算法和解码实现复杂程度,根据软硬件协同设计思想提出了一种结构划分合理的AVS高清视频解码器软硬件分区结构。根据AVS算法的特点该结构将宏块层以上部分的元素解析划归到软件解码中,将宏块层解码划为硬件处理。经验证,该结构设计可实现AVS高清码流解码,并在C语言编写的硬件平台仿真程序中得以实现。

| Abstract: | The architecture of video decoder is transforming from dedicated hardware to HW/SW partition owing to the powerful process of hardware and the flexibility and programmability of software. This paper presents a rational HW/SW partition architecture based on the analysis of the AVS algorithms and the complexity of AVS decoding. According to the characteristics of AVS algorithms, the decoding of AVS syntax elements above block layer is realized through software and the hardware is responsible for block decodin... |
