| 摘 要： | 提出一种基于ARM ESL平台的软硬件协同的设计方法,并进行了整个AVS解码系统的设计和仿真验证.在具体的软硬件划分中,通过采用硬件加速AVS亮度插值模块,合并了二分与四分之一亮度插值的软件算法, 并用DMA控制器改进插值的硬件结构,从而改善了系统的整体性能.实验中比较十帧720x576的AVS解码图像在原始纯软件环境,同软硬件协同系统的仿真结果.仿真结果说明新的AVS解码系统的体系结构提高了AVS解码系统的整体性能,为AVS系统的软硬件协同设计提供了有益的参照.

| Abstract: | A new hardware/software codesign method based on ARM ESL platform.This method is used to design and verify AVS video decoder via the simulation.In software/hardware partitions,the luminance interpolation is implemented in hardware with combination of the half and quarter-interpolation.This paper also presents the improvement of interpolation hardware architecture and the incorporation of DMA controller.All these lead to better overall system performance.In the experiments,it compares the simulation performa... |
