在线动态可重构SoPC系统设计与实现

On-Line Dynamic Reconfigurable SoPC System Design and Implementation

针对SoPC系统远程实时更新的实际需要,设计并实现了一种基于Virtex-ⅡPro XC2VP30平台的在线动态可重构SoPC系统。该系统应用IRL设计理念和局部动态重构技术,利用Xilinx公司的ISE8.2、EDK8.2、PlanAhead10.1和SystemGen-erator10.1等开发工具,对算术运算和音频处理模块进行局部动态重构和远程实时更新。经实验结果表明,该系统能够通过局部动态重构技术使电路重构的时间缩短到1s左右,还能够完成配置文件的远程在线实时更新,适用于地理位置较偏远、对安全性要求较高的场合。

In view of actual requirement of SoPC reconfigurable SoPC system based on the Virtex-Ⅱ system updating remotely in real time, an on-line dynamic Pro XC2VP30 was designed and implemented. The system applies IRL design methodology and partial dynamic reconfigurabte technology, partially reconfigures and updates arithmetic operation and audio processing modules remotely in real time, with ISE8.2, EDK8.2, PlanAheadl0.1 and SystemGeneratorl0.1 of Xilinx Inc. The result shows that this system which is suitable for the remote location or the situation requiring for higher security, can shorten the reconfiguration time to 1 s by implementing partial dynamic reconfigurable technology, and update configuration files on-line remotely in real time.
