Abstract:
1. An apparatus, comprising: an integrated circuit (IC) configured to load a first data byte of a first disk block and a first data byte of a second disk block from a storage device to an arithmetic logic unit; the IC further configured to XOR the first data byte of the first disk block and the first data byte of the second disk block to generate a first result; the IC further configured to store the first result in a results buffer; the IC further configured to iteratively repeat loading intermediate data bytes corresponding to the first disk block and intermediate data bytes corresponding to the second disk block from the storage device to the arithmetic logic unit; the IC further configured to XOR the intermediate data bytes corresponding to the first disk block and the intermediate data bytes corresponding to the second disk block to generate intermediate results; the IC further configured to generate a RAID syndrome based on, at least in part, the intermediate results.
