摘要
在早期获取部分可重构EAPR(Early Access Partial Reconfiguration)方法的基础上,研究实现局部动态自重构系统的方法和流程。设计的系统有两个可重构区域,每个区域有两个重构模块,利用Virtex-4上集成的PowerPC硬核微处理器控制内部配置访问端口ICAP(Internal Configuration Access Port)完成自重构。通过在Xilinx ML403开发板上进行验证,实现了系统的自重构功能。系统对部分资源的分时复用提高了系统的资源利用率,高的配置速率缩短了系统的配置时间。
The design method and flow of the partial dynamic self-reconfiguration system were studied and implemented based on the reconfiguration design of EAPR.The system included two reeonfigurable regions, each with two reconfigurable modules. The PowerPC hard core microprocessor that was integrated in the Virtex-4 was used to control the ICAP to complete self-reconfig- urable. Through ML403 board of Xilinx, the function of self-reconfiguration was verified. The time devision multiplexing of part of the resource improves the resouce utilization, and the high configuration speed shortens the configuration time.
