摘要：
A redundant array of independent disk (RAID) stack loads a parity block of RAID data from a main memory into a first register of a processing device and loading the parity block into a cache memory of the processing device. The RAID stack loads a first data block of the RAID data from the main memory into a second register of the processing device without loading the first data block into the cache memory of the processing device. The processing device performs a first parity calculation based on the parity block of the first register and the first data block of the second register.
