Abstract
A register structure in an integrated circuit includes a first register element to store a first copy of data, a second register element to store a second copy of the data, and storage cells to store copies of a parity value of the data. The register structure also includes parity computing circuitry, coupled to the first and second register elements, to generate respective parity values of the first and second copies of the data. The register structure further includes a selection circuit to select between the first and second copies of the data based on a comparison of the respective parity values of the first and second copies of the data to a majority value of the copies of the parity value stored in the storage cells.
