摘要： 可重构计算系统中软硬件资源的管理缺乏统一的机制，资源不能被有效利用。为此，设计并实现一种硬件任务模型，为上层软件提供统一的硬件接口，使操作系统能够对软硬件任务进行统一管理，并给出硬件任务下载器的实现结构及工作流程。实验结果表明，该硬件任务模型的运行效率较高，硬件任务下载器能较大地提高硬件任务的下载速率。

Abstract: The management of hardware resources and software resources lacks a unified mechanism. To solve this problem, the hardware part of the reconfigurable computing system is discussed, and a hardware task model with unified interface is proposed to allow the operating system a unified management of hardware and software tasks. An efficient hardware task downloader is designed to increase the download speed of hardware tasks. Experimental results show that the proposed hardware design of the task model is completely feasible and efficient, and hardware task downloader can significantly improve the hardware task download speed.

Key words: reconfigurable computing, software/hardware hybrid system, Field Programmable Gate Array(FPGA), hardware downloader
