Error correction apparatus and associated method utilizing parellel processing

摘要

Apparatus, and an associated method, for performing error-correction operations to correct errors in a block of block-encoded data. Two ALUs are operable in parallel to perform finite-field mathematical operations and to calculate addresses used pursuant to the error-correction calculations. Instructions pursuant to which the ALUs are operable are stored in a memory device. The instructions are retrieved during operation of error-correcting calculations. The manner by which the error-correcting apparatus operates is alterable by appropriate alteration of the instructions stored at the memory device.
