WebMay 23, 2024 · In this paper, we reverse engineer the structure of the directory in a sliced, non-inclusive cache hierarchy, and prove that the directory can be used to bootstrap conflict-based cache attacks on the last-level cache. We design the first cross-core Prime+Probe attack on non-inclusive caches. This attack works with minimal … WebWhether a block present in the upper cache layer can also be present in the lower cache level is governed by the memory system's inclusion policy, which may be inclusive, exclusive or non-inclusive non-exclusive …

The merit of inclusive policy is that, in parallel systems with per-processor private cache if there is a cache miss other peer caches are checked for the block. If the lower level cache is inclusive of the higher level cache and it is a miss in the lower level cache, then the higher level cache need not be searched. This … See more Multi-level caches can be designed in various ways depending on whether the content of one cache is present in other levels of caches.
