Abstract
Method and system for receiving each data element of an array once and simultaneously forming an EDC error detection term, two ECC P-parity checkbytes and two ECC-Q-parity checkbytes for the array. Each data element is read once from memory and is received by an EDC processor, by an ECC-P processor and by an ECC-Q processor and is processed in parallel and substantially simultaneously by the three processors to form an EDC error detection term and the ECC-P-parity and ECC-Q-parity checkbytes, using shift registers with feed-back and/or weighted summation of selected register contents.
