Abstract

A time-based system and method are provided for controlling the management of cache memory. The method accepts a segment of data, and assigns a cache lock-time with a time duration to the segment. If a cache line is available, the segment is stored (in cache). The method protects the segment stored in the cache line from replacement until the expiration of the lock-time. Upon the expiration of the lock-time, the cache line is automatically made available for replacement. An available cache line is located by determining that the cache line is empty, or by determining that the cache line is available for a replacement segment. In one aspect, the cache lock-time is assigned to the segment by accessing a list with a plurality of lock-times having a corresponding plurality of time duration, and selecting from the list. In another aspect, the lock-time durations are configurable by the user.
