Abstract

1359239 Data processing system; error detection INTERNATIONAL BUSINESS MACHINES CORP 22 Nov 1972 [30 Dec 1971] 54048/72 Heading G4A A data processing system includes a central data processing unit (not shown), a peripheral unit control processor 1 having an internal store 2 and being arranged to execute error detection programs relating to errors in its associated peripheral units 3, an interface processing unit 4 having an internal store 5, and an external store 6 connected to the interface processor and arranged to store error detection programs, the arrangement being such that the interface processor 4 transfers a selected error program from the external store 6 to its internal store 5 and the control processor 1 transfers the error program from the interface processor store 5 to its internal store 2 for execution. The arrangement allows error diagnosis of the peripherals to be performed independently of the central processing unit. During normal operation of the system the interface processor 4 is controlled by the central processor (CPU) via line 10. A special code is entered via keyboard 8 to inform the CPU that processor 4 is unavailable. A list of available error programs stored on tape 6, it being stated that a magnetic disc may be used, is read into processor 4 and displayed at 7. One of the programs is selected using the keyboard 8 and is read from store 6 into the internal store 5. The peripheral processor 1 is then informed that an error program has been selected. Processor 1, after executing each instruction originating from the CPU, checks whether an error program has been selected and, during periods when it is otherwise unoccupied, transfers the program into its internal store 2 for execution also during periods when it is otherwise unoccupied. Following execution of an error program any resulting data is transferred to processor 4 for display at 7. Further error programs may then be selected by the keyboard 8. Alternatively several error programs may be chained together, a subsequent program being selected by a program just finishing and being written into store 2 as above to replace the earlier program.
