WebQ. Consider a main memory with five page frames and the following sequence of page references: 3, 8, 2, 3, 9, 1, 6, 3, 8, 9, 3, 6, 2, 1, 3. which one of the following is true with respect to page replacement policies First-In-First-out (FIFO) and Least Recently Used (LRU)? A. Both incur the same number of page faults. Weba cost-effective cache replacement policy. Specifically, we use reinforcement learning (RL) to learn a last-level cache (LLC) replacement policy. The RL algorithm takes into consideration a collection of features that can be easily obtained at the LLC without modifying the processor’s control and data path.

WebTo implement an LRU cache we use two data structures: a hashmap and a doubly linked list. A doubly linked list helps in maintaining the eviction order and a hashmap helps with O (1) lookup of cached keys. Here goes the algorithm for LRU cache. If the element exists in hashmap. move the accessed element to the tail of the linked list. WebNov 9, 2024 · Add a new entry in HashMap and refer to the head of the list. And, we'll do two steps after a cache hit: Remove the hit element and add it in front of the list. Update HashMap with a new reference to the front of the list. Now, it's time to see how we can implement LRU cache in Java! 3. saffron flower beauty photoshoot

The data or contents of the main memory that are used frequently by CPU are stored in the cache memory so that the processor can easily access that data in a shorter time. Whenever the CPU needs to access memory, it first checks the cache memory.
