摘要

本研究提出了一种可复用的多核NUCA缓存故障重映射方案。它在不可重用的块中复制数据，通过在主块周围形成动态重映射集群，确保完全的错误覆盖和最小的延迟。在Multi2Sim 5.0中的模拟表明，与现有技术相比，最后一级缓存的命中率提高了18.64%，延迟降低了20.79%，面积增加了3.17%，泄漏功率减少了5.35%，动态功率开销减少了3.34%。

Latency Aware Fault Tolerant Cache in Multicore Using Dynamic Remapping Clusters

This work proposes a re-usability aware fault remapping scheme for multicore NUCA cache. It replicates data in non-reusable blocks to ensure full error coverage and minimum latency, by forming dynamic remapping clusters around the home tiles. Simulations in Multi2Sim 5.0 claim up to 18.64% increase in hit ratio and 20.79% decrease in latency in last-level cache over the existing techniques with 3.17% area, 5.35% leakage power and 3.34% dynamic power overheads.
