Abstract

Video decoders used in emerging applications need to be flexible to handle a large variety of video formats and deliver scalable performance to handle wide variations in workloads. In this paper we propose a unified software and hardware architecture for video decoding to achieve scalable performance with flexibility. The light weight processor tiles and the reconfigurable hardware tiles in our architecture enable software and hardware implementations to co-exist, while a programmable interconnect enables dynamic interconnection of the tiles. Our process network oriented compilation flow achieves realization agnostic application partitioning and enables seamless migration across uniprocessor, multi-processor, semi hardware and full hardware implementations of a video decoder. An application quality of service aware scheduler monitors and controls the operation of the entire system. We prove the concept through a prototype of the architecture on an off-the-shelf FPGA. The FPGA prototype shows a scaling in performance from QCIF to 1080p resolutions in four discrete steps. We also demonstrate that the reconfiguration time is short enough to allow migration from one configuration to the other without any frame loss.
USHA:用于视频解码的统一软硬件架构
新兴应用程序中使用的视频解码器需要灵活地处理各种视频格式,并提供可扩展的性能,以处理工作负载的广泛变化。本文提出了一种统一的视频解码软硬件架构,以实现可扩展性和灵活性。我们架构中的轻量级处理器模块和可重构硬件模块使软件和硬件实现能够共存,而可编程互连使模块能够动态互连。我们的面向过程网络的编译流程实现了与实现无关的应用程序分区,并实现了视频解码器在单处理器、多处理器、半硬件和全硬件实现之间的无缝迁移。应用程序服务质量感知调度器监视和控制整个系统的操作。我们通过现成的FPGA上的架构原型证明了这一概念。FPGA原型显示了从QCIF到1080p分辨率的性能缩放,分为四个步骤。我们还证明了重新配置时间足够短,可以从一种配置迁移到另一种配置而不会有任何帧丢失。
