Claim Text:
1. A method to increase exclusive-OR (XOR) computation speed, comprising: reading a line of data from a line of memory, wherein intended data is specified by a random location and a random size within the line of memory; moving the line of data into temporary storage; multiplexing the line of data and a zero using a control signal to output a line of adjusted data, wherein a starting index of the intended data within the line of adjusted data corresponds to an initial point within an XOR buffer; performing an XOR operation on the line of adjusted data and a line of data read from the XOR buffer to obtain a modified line of XOR data; and writing the modified line of XOR data back to the XOR buffer at the same buffer locations as the line of data read from the XOR buffer.
