Method of adaptive read cache pre-fetching to increase host read throughput
TLDR
In this article, the authors employ receiving an operational parameter characteristic of a storage device, and adapt a read cache pre-fetch depth based in part on the operational parameter, which can be used to generate an operational parameters and vary the read cache depth in response to the operational parameters.Abstract:
Exemplary systems, methods, and devices employ receiving an operational parameter characteristic of a storage device, and adapting a read cache pre-fetch depth based in part on the operational parameter. An exemplary device includes a read cache memory and a read cache pre-fetch adaptation module operable to generate an operational parameter and vary read cache pre-fetch depth in response to the operational parameter.read more

Systems and methods for adaptive prefetching
TL;DR: In this article, a dynamically adaptive prefetching mechanism based on block access history information and prior effectiveness of pre-fetching is provided. But this mechanism does not take into account prefetch efficiency; a dynamic value indicating the usefulness of past prefetches, prefetch wastage, in conjunction with prefetch resources available at any point in time, determine the number of blocks to read-ahead during a prefetch.

Method and apparatus for replacing cache lines in a cache memory
TL;DR: In this paper, a cache memory replacement algorithm replaces cache lines based on the likelihood that cache lines will not be needed soon, and the cache lines selected for replacement contain the most speculative data in the cache that is least likely to be needed.
