PURPOSE:To delete hardware in an instruction storing system, in which an instruction for operating information processing is temporarily stored, read out, and checked and outputting as the operating instruction by previously forming error detecting information against an instruction by software processing, and storing the information as continuous codes. CONSTITUTION:An instruction code 1 generates a code 3 for storage to a storage device through a module 2 for generating an error detect code by software. The error detect code generating module 2 contains a bit pattern analyzing section 4, parity generating section 5, and parity code burying section 6 and, by means of them, a parity code of, for instance, 4 bits is obtained against the instruction code 1. The code 3 for storage is stored in the storage device by the writing module 8 of the storage device, after the parity bit is fitted to the end of the instruction code 1. It is also possible to generate an error correct code (ECC code) by the software as an error detect code instead of a parity check code. |
