摘要:
One embodiment of the present includes a electronic data storage card having a Reed Solomon (RS) decoder having a syndrome calculator block responsive to a page of information, the page being organized into a plurality of data sections and the overhead being organized into a plurality of overhead sections. The syndrome calculator generates a syndrome for each of the data sections. The decoder further includes a root finder block responsive to the calculated syndrome and for generating at least two roots, a polynomial calculator block responsive to the at least two roots and operative to generate at least one error address, identifying a location in the data wherein the error lies, and an error symbol values calculator block coupled to the root finder and the polynomial calculator block and for generating a second error address, identifying a second location in the data wherein the error(s) lie.
