ABSTRACT:
One embodiment of the present invention provides a system that facilitates detecting and correcting errors. The system operates by receiving a data packet comprised of p words on a communication pathway, wherein each bit of a word is received on a separate data line in a set of data lines that comprise the communication pathway. The system also receives a time signature t on the communication pathway, wherein t contains per-bit error information for the p words in the data packet. As the data packet is received, the system performs an error-detection operation on each data bit of the data packet in parallel, wherein the error-detection operation generates per-bit error information for each bit position across the p words in the data packet. Finally, the system compares the generated per-bit error-information with the corresponding per-bit error information in the time signature t to determine if there exists an error.
