A redundant array of independent disk (RAID) stack loads a first parity block of RAID data into a first memory address of a main memory of a data processing system. A first parity calculation is performed on a first plurality of data blocks of the RAID data with the first parity block loaded from the first memory address of the main memory into a register of the processor of the data processing system and a cache memory associated with the processor. The RAID stack loads subsequent parity blocks of RAID data into subsequent memory addresses of the main memory, where a difference between the first memory address and the subsequent memory addresses equals to one or more multiples of an alias offset associated with the cache memory. A second parity calculation is performed on a second plurality of data blocks and the second parity block of the RAID data.
