PARTITIONED CACHE REPLACEMENT ALGORITHMCache replacement policy mechanism for updating cache entries of a partitioned cache using a pseudo-LRU (least recently updated) scheme for partial updating of LRU bits.Hughes, WilliamLepak, Kevin
For direct mapping, there is only one possible line for any particular block, and no choice is possible(直接映射对于每一块只有确定一行,没有别的可能性) For the associative and set-associative mappings, a replacement algorithm is needed, which must be implemented in hardware(对于全相联映射和组相...
A memory area thatisonly addressable by the kernel through mapping portions into its own address space. Thisisforexample used by i386 to allow the kernel to address the memory beyond 900MB. The kernel willsetup special mappings (page table entries on i386)foreach page that the kernel needs t...
Starting in Oracle Database 12c Release 1 (12.1.0.2), the big table cache is an optional section of the default pool that uses a temperature-based, object-level replacement algorithm. In single-instance and Oracle RAC databases, parallel queries can use the big table cache when theDB_BIG_TA...
This complicates both the policy and the implementation of the replacement algorithm. The cache management software should evict from the code cache one or more segments that have not been used recently. The evicted segments must free enough space to accommodate the new code without wasting “too...

A replacement method is provided for improving the hit rate and testability of a page address translation cache (PATC). The replacement scheme uses a modified FIFO replacement algorithm. A circular shift register has a pointer which points to each of a predetermined number of translation descriptors...
Kao and Lee (2007) propose a cache replacement algorithm for use in a proxy which does transcoding. The transcoding proxy generates different bitrate encodings of the same video and takes into account the byte size and popularity of each encoding when caching (e.g., videos more often access ...
