论文摘要
最后一级缓存（LLC）分区是一种技术，可以提供时间隔离和低最差的延迟延迟（WCL）范围，当核心访问多层安全至关重要系统中的共享LLC时。缓存分区的典型方法涉及将单独的分区分配给独特的核心。对这种方法的核心批评是其对缓存存储的利用率不佳。当今，整合大量核心的趋势加剧了这个问题，因此我们被迫考虑共享的LLC分区以进行有效部署。这项工作提出了一种在多个内核之间共享LLC分区的方法，同时能够提供低WCL界限。
Last-level cache (LLC) partitioning is a technique to provide temporal isolation and low worst-case latency (WCL) bounds when cores access the shared LLC in multicore safety-critical systems. A typical approach to cache partitioning involves allocating a separate partition to a distinct core. A central criticism of this approach is its poor utilization of cache storage. Today's trend of integrating a larger number of cores exacerbates this issue such that we are forced to consider shared LLC partitions for effective deployments. This work presents an approach to share LLC partitions among multiple cores while being able to provide low WCL bounds.
