加速器用于加速要求严格的计算应用程序。然而，设计人员发现集成硬件和软件通信接口是一个挑战。本文研究了可重构嵌入式系统中的计算集成方法。通过集成链接器，硬件网表文件、任务和初始文件将被合并为一个执行文件，该文件可以在所提出的可重构平台上执行。任务和硬件功能通过程序段前缀分隔，用于记录软硬件资源的交互信息。当执行器在目标嵌入式环境上操作时，隐式硬件函数调用将用于通过任务代码中的硬件管理单元桥接来调用硬件函数。该集成方法已在协同设计平台中实现，并通过视频压缩应用验证了软硬件间通信的有效性。
Accelerators are used to speed up demanding computational applications. However, designers find integrating hardware and software communications interface being a challenge. In this paper, the integration methods for computing in reconfigurable embedded systems are explored. Through integration linker, hardware net-list files, tasks, and initial file will be combined into one execution file, which can execute in the proposed reconfigurable platforms. Tasks and hardware functions are segregated by program segment prefixes, designed to record interaction information of hardware and software resources. When the executor operates on the target embedded environment, the implicit hardwire-function call will be used to invoke hardware functions by hardware management unit bridging in the task codes. The integrating methodology has been implemented in the co-design platform, and this work verifies communication effectiveness between hardware and software through video compression applications.
