摘要:

针对重构文件的大小、动态容错时隙的长短、实现的复杂性、模块间通信方式、冗余资源的比例与布局等关键问题进行了分析。并对一些突出问题,提出了基于算法和资源多级分块的解决方法,阐述了新方法的性能,及其具有的高灵活性高、粒度等参数可选择、重构布线可靠性高、系统工作频率有保障的优点。

Abstract:

This paper analyzes several methods in the aspects of size of reconfigurations,reconfiguration interval,implement complexity,inter-module communication,routing and proportion of spare resources.To solve some main problems,we have proposed a method based on the multiple division of algorithm and resources and analyzed its performance.This method is flexible and some parameters like granularity are optional.Routing of reconfiguration is reliable and can ensure the operation frequency of the system.

Key words: fault tolerance;dynamic reconfiguration;Retiming;STARs
