Hierarchical lru

WebLeast recently used(LRU): replace the block that has been unused for the longest time. Ok for 2-way, maybe 4-way. Too hard beyond. Approximated LRU: “Hierarchical” LRU. Example 4-way: 1 bit determines the pair with the oldest (LRU) pair of blocks. 1 bit determines the LRU block within the pair. Diego Fabregat Shared memory 15 / 34 WebIn order to improve the convenience of replacing faulty equipment on the route and realize LRU(Line Replaceable Unit) level planning reasonably and effectively, a LRU hierarchical division method based on optimal granularity level is proposed.
