Verfahren zur Reset-Erzeugung in Datenverarbeitungsanlagen

摘要

To avoid unnecessary down time, in data processing systems, particularly numerical control systems, the dynamic read-write memory (D) is only rewritten if a reset signal (RU) which is caused by a power failure is present. For reset signals with other causes, the central processor (CPU) recognises from test information (WT) which is produced in the dynamic read-write memory (D) that its content has been completely retained.
