Abstract
Data is divided into parts and each part provided to a different processor. Each processor processes the provided data part to produce a partial CRC result. The partial CRC results from each of the different processors are XORed to produce a CRC of the data.
Claims11
A method comprising:
- dividing data into parts and providing each part to a memory buffer of a different machine data processor, each data part comprising a string of bits, the string of bits comprising sequences of bits not representing data values separating portions of the string representing data values;
- each processor processing a provided data part to produce a partial CRC result;
- and
- xoring partial CRC results from each of the different processors to produce a CRC of the data.
