ABSTRACT:
An information handling system includes one or more processing units, a memory management unit, connected to the processor, and to a memory system, a cache management unit, one or more levels of cache memory associated with the one or more processors, an I/O controller connected to a bus which connects to the processing units and to the memory systems and to cache, the I/O controller controlling various input/output devices such as a keyboard, a mouse, a display device, communications adapters and the like, and a remote storage controller for controlling one or more direct access storage devices. Cache management unit further includes an optimized block transfer circuit for identifying starting and ending addresses of modified segments of data blocks and the cache unit.
