Abstract
An application accelerator (AA) unit that in one embodiment is part of an I/O processor (IOP) integrated circuit. The AAU includes logic circuitry for improving the performance of storage applications such as Redundant Array of Inexpensive Disks (RAID). A boolean unit performs operations such as exclusive-or (XOR) on multiple blocks of data to form the image parity block which is written to the redundant disk array. The AAU is associated with a memory-mapped programming interface that allows software executed by a core processor in the IOP to utilize the AAU for accelerating RAID storage applications as well as local memory DMA-type transfers, using the descriptor construct.
