Abstract:An optimization method was described to reduce the exclusive-or operations of the binary Vandermonde code.The encoding and decoding operation of the binary Vandermonde code was the bitwise exclusive-or.According to the distribution of the ones in the binary matrix and the relationship between the vectors
the calculation sequence of the parity chunk was determined ultimately.The test showed that the method can reduce the exclusive-or operations significantly by about 30%.Meanwhile
the method can be extended to other exclusive-or based storage systems
