摘要: 在航空航天等领域使用的系统,在发生系统错误的情况下,很难实现人工修复。本文在介绍众核系统NoC和容错技术的基础上,提出一种基于众核系统片上网络的自动修复方案。该方案在检测到系统发生永久性错误的时候,通过重新映射,重新布局布线完成系统功能的恢复,延长系统在没有人工干预情况下的使用时间。

关键词: 片上网络, 航天器, 容错技术, 自修复

Abstract: Human-induced restoration is almost impossible when fault occurs in system of some fields, such as in space. Based on NoC structure and fault-tolerance technologies, this paper proposes a design of self-repairing system of many-core structure. The scheme intents to extend system lifetime without human-induced restoration by remapping when permanent fault occurs.

Key words: NoC, spacecraft, fault-tolerance technologies, self-repairing
