A disk controller includes memory that is accessible by both a microprocessor and hardware parity logic. Parity-related operations are identified by scenario, and parity coefficient subsets are stored in a memory table for each different parity-related calculation scenario. To perform a particular parity-related...http://www.google.com/patents/US6687872?utm_source=gb-gplus-sharePatent US6687872 - Methods and systems of using result buffers in parity operations
