ABSTRACT:
Cache management strategies are described for retrieving information from a storage medium, such as an optical disc, using a cache memory including multiple cache segments. A first group of cache segments can be devoted to handling the streaming transfer of a first type of information, and a second group of cache segments can be devoted to handling the bulk transfer of a second type of information. A host system can provide hinting information that identifies which group of cache segments that a particular read request targets. A circular wrap-around fill strategy can be used to iteratively supply new information to the cache segments upon cache hits by performing pre-fetching. Various eviction algorithms can be used to select a cache segment for flushing and refilling upon a cache miss, such as a least recently used (LRU) algorithm or a least frequently used (LFU) algorithm.
