Abstract
A method and system for increasing the efficiency of a virtual memory operating system is provided. In hardware assisted virtual memory, paging systems the preferred embodiment reduces the need for paging to or from non-memory devices by compressing and concatenating inactive regions in place. The compressed and concatenated regions are then queued for paging in the traditional virtual memory methodology. In this system, RAM memory made available by reducing the size of inactive regions is available immediately for use by the standard virtual memory paging system.
