Abstract
An error correction code apparatus has a processor located (on-chip) L2 tag and error correction and detection, and an off-chip L2 data array and second error correction and detection, the chips connected by a data bus. For a write operation, ECC bits are generated and transmitted with data to the off-chip array. New ECC bits are generated and compared to the original ECC bits. Correction is accomplished if needed. For a read operation, stored ECC bits and data are retrieved from the off-chip data array and transmitted to the core processor. New ECC bits are generated and compared to the original ECC bits. Correction is accomplished if needed.
