Method and apparatus for error detection/correction

1. Field A method of detecting errors in a datapath in accordance with the invention includes generating a plurality of electronic signals, computing a first at least one data-signature value based, at least in part, on the plurality of electronic signals and staging the plurality of electronic signals and the first at least one data-signature value. The method further includes transmitting the plurality of electronic signals via at least one intervening stage of circuitry, computing a second at least one data-signature value based, at least in part, on the plurality of electronic signals, and comparing the first at least one data-signature value the said second at least one data-signature value.
