Abstract: An information processing apparatus which make it possible to confirm an error recovery event. A device proxy server as an information processing apparatus is connected to a printer and a client PC via a network. The device proxy server receives an event message indicative of an event having occurred in a printer. The received event message is transferred to a client PC. When the event message transferred to the client PC is related to an error event indicative of an error having occurred in the printer, the device proxy server monitors whether or not the error event has been eliminated in the printer. When the error event is eliminated in the printer, the device proxy server sends an error recovery message indicative of elimination of the error event to the client PC.

Abstract: An integrated circuit may have an array of memory elements. Each memory element may have multiple memory cells. Each memory element may have a voting circuit that receives signals from the memory cells in that memory element. The voting circuit can produce an output based on the signals. The signals stored by the memory cells of each memory element may be redundant so that the voting circuit can produce an accurate output even in the event that a radiation strike causes some of the memory cells to flip their states to erroneous values. The memory elements may be based on memory cells such as static random-access memory cells and thyristor-based cells.

Abstract: Disclosed is a data processing system capable of detecting a sign of abnormality in such a manner as to increase the degree of safety and availability of the system. The data processing system uses a prediction circuit that detects a sign of abnormality in accordance with a cumulative history of significant events encountered during the processing of CPUs. The prediction circuit retains latest notification timing information about periodic notification from the CPUs in association with the CPUs, acquires elapsed time from the latest notification timing at predetermined intervals, and successively retains history information corresponding to changes in the elapsed time from a target value in association with the CPUs. When the retained history information reaches a predetermined threshold value, the prediction circuit concludes that there is a sign of abnormality.
