CONTROL METHOD FOR ERROR DETECTION/CORRECTION DEVICE, ERROR DETECTION/CORRECTION DEVICE, INFORMATION PROCESSING SYSTEM, CONTROL PROGRAM FOR THE ERROR DETECTION/CORRECTION DEVICE AND DATA PROCESSOR

摘要

PPROBLEM TO BE SOLVED: To attain high level data processings requiring the merge processing of data in each processor in an error detection/correction technology for processing the error check unit data of an ECC, by sharing the data with a plurality of processors. PSOLUTION: In a plurality of data processors 40, interposed in a data communication path for processing the data units of ECC check by sharing them, partial syndromes, generated by each of the data processors 40 and rewrite information relating to the data after error correction, are switched via an information exchange bus 50 so that high-level processings accompanied by data-merge processing, such as read-modify-write can be performed inside each data processor 40.
