Abstract
A compressed memory system includes a cache, and compressed memory including fixed size storage blocks for storing both compressed data segments and fixed size storage blocks defining a virtual uncompressed cache (VUC) for storing uncompressed data segments to enable reduced data access latency. The compressed memory system implements a system and method for controlling the size of the VUC so as to optimize system performance in a manner which permits the avoidance of operating system intervention which is required in certain circumstances for correct system operation. The system solves-these problems by implementing one or more thresholds, which may be set by the operating system, but which, after being sets control the size of the VUC independently of the operating system or other system software.
