可重构的嵌入式虚拟仪器设计方法

Reconfigurable Design Method for Embedded Virtual Instrument

为了使运行期的器件实现快速逻辑重建,设计一种嵌入式虚拟仪器(EVI)动态可重构方法。该方法以动态可重构IP作为基本模块,运行期间对组成系统的IP进行动态替换以实现硬件重构,通过EVI中间件和配置信息库实现软件重构。测试结果表明,该方法能降低开发成本,缩短开发周期,实现不同场合的测试要求。

In order to implement instrument configurate quickly during the time of operating, this paper designs a dynamic reconfiguration scheme for Embedded Virtual Instrument（EVI）. It uses a dynamic reconfigurable IP as a basic module and dynamically replaced for form system IP during the run to achieve the hardware reconfiguration. The design uses EVI middleware and configuration store to achieve the software reconfiguration. Test results demonstrate that the method can reduce the cost and cycle of exploitation, implement test requirement for different situation.
