Automatic error correction system for data processor - executes each programme sequence twice and compares results

摘要

The error detection and correction system for programme errors in a data processor, has each programme sequence executed twice, with a significant code used to represent the result of each sequence execution. These codes are compared and the next programme sequence is requested when the codes are in agreement. The programme sequence is recalled when the codes vary from each other, with the programme sequence data and the corresponding addresses being stored. Pref. a storage register (A, B, C) has a memory zone for the sequence data and the addresses and a register for storing the code word signifying the result.
