一种基于动态迁移技术的寄存器保护方法

Register Protecting Method Based on Live Migration Technology

在强辐射环境中,寄存器会受到高能粒子冲击而发生位翻转导致寄存器内容发生变化,称这种现象为寄存器故障。对关键寄存器进行定义,提出一种寄存器保护模型,通过动态申请系统当前空闲的寄存器作为关键寄存器的备份,在运行过程中运用动态迁移技术对关键寄存器进行保护,使寄存器自身具有一定的容错能力。

In the radiation-hardened environment, registers are prone to SEU phenomenon because of energetic particle impaction, called register faulty. This paper proposes a method of register protection, dynamically requests the currently idle register to be the backup of the essential register as well as taking advantage of live migration technology during program progress to introduce protection for the essential registers, enabling registers themselves to have kind of fault-tolerant ability.
