WebFor four-way and eight-way associativity, binary tree pseudo-LRU is commonly used, though some embedded systems might implement true LRU as such is easier to analyze for worst-case execution time. Binary tree pLRU is relatively simple to implement because an access to a given way will always merely set/clear specific bits. WebPLRU is the name of the class of cache replacement deriving from LRU, but instead of using an exact measure they use an approximate measure of the recently used lines. … WebHard real-time systems must obey strict timing constraints. Therefore, one needs to derive guarantees on the worst-case execution times of a system's tasks. In this context, predictable behavior of system components is crucial for the derivation of ... bourdib 2019

During the cache access, if block A is hit then the flag[0] and flag[1] are both set to 1. It guides the PLRU algorithm to pick the PLRU candidate from the right subtree of flag[0], as the block A in the left subtree is just referenced.
