An integrated circuit and associated methods operable therein to provide hardware assist to RAID storage management controllers. The RAID assist integrated circuit offloads a general purpose processor of the storage controller from the responsibility and processing associated with address mapping. RAID geometry and addressing parameters may be stored in a register file or similar storage associated with the RAID assist integrated circuit so as to permit logic therein to automatically map host request parameters to corresponding low level device commands and status. The RAID assist integrated circuit may incorporate scatter/gather list processing features and address mapping features. Queue management features may also be integrated therein to provide buffered queueing of commands and status exchanged between the host system and the storage controller. In addition, host interface features, storage device interface features and RAID redundancy (e.g., parity) assist features may be integrated within the RAID assist integrated circuit.
