The LRU-like algorithm was proposed for the block management to enhance the direct-mapped cache scheme. Base on the LRU-like algorithm, the Least-recently-used Block Filtering cache (LBF cache), which can filter LRU blocks, is designed. From the point of cache usage rate, the LBF cache uses LRU-like algorithm to allocate and replace blocks, and evicts the blocks whose usage shows the least efficiency. After the simulation, the performance of LBF cache shows better performance than typical cache schemes with similar architecture (such as victim cache and assist cache).
