摘要: 为使嵌入式系统具备远程在线更新和维护能力,基于软/硬件统一多任务编程模型,应用互联网可重构逻辑设计方法设计并实现支持远程动态重构的嵌入式系统。提出的统一多任务编程模型为软/硬件任务提供统一接口和管理方式,可降低设计可重构系统的复杂度,同时远程重构功能增加了系统远程在线更新和维护的能力。实验结果表明,该模型可用于远程可重构系统的设计,同时硬件任务也具有较快的加速比。

Abstract: This paper designs an embedded system with remote and dynamic reconfigurable ability based on reconfiguration technology and Internet Reconfigurable Logic(IRL) method. A software/hardware unified multi-task programming model which greatly reduces the complexity of reconfiguration system is designed to provide unified interface and management for software/hardware task. The remote features increase the ability to upgrade and maintain the system remotely by Internet. Experimental results show the profits of the programming model and the good speedup of the hardware task.
