本文认为,实现低成本的硬件技术,这将允许容忍临时故障的粗粒度可重构架构(CGRAs)的数据路径的可能性。我们的目标是使用比常用的重复或三重方法更少的硬件开销。所提出的技术依赖于并发错误检测,通过使用剩余代码模3和重新执行的最后一个操作,一旦检测到错误。我们选择DART架构作为研究这种方法保护其数据路径的效率的工具。仿真结果证实了所提出的方法相对于重复的硬件节省。
This paper considers the possibility of implementing low-cost hardware techniques which would allow to tolerate temporary faults in the datapaths of coarse-grained reconfigurable architectures (CGRAs). Our goal was to use less hardware overhead than commonly used duplication or triplication methods. The proposed technique relies on concurrent error detection by using residue code modulo 3 and re-execution of the last operation, once an error is detected. We have chosen the DART architecture as a vehicle to study the efficiency of this approach to protect its datapaths. Simulation results have confirmed hardware savings of the proposed approach over duplication.
