Abstract:
ECC (error correcting code) error-correcting apparatus for error-correcting a block of digital data encoded according to a selected encoding technique, said ECC error-correcting apparatus comprising:a finite-field ALU coupled selectively to receive an error-location indication and an error-syndrome indication, said finite-field ALU for performing finite-field mathematical calculations;an integer ALU operable in parallel with said finite-field ALU, said integer ALU at least for performing address calculations; anda sequencer coupled to said finite-field ALU and to said integer ALU, said sequencer at least selectably operable to cause application of instructions to said finite-field ALU and to said integer ALU, said finite-field ALU and said integer ALU together operable to correct data errors of the block of data.
