Abstract:
The present invention is directed to a method and system for use in a computing environment to monitor parameters and detect abnormalities. A monitoring system for monitoring a process may include a signature creation module (22) for creating a signature representative of the process, a signature updating module (24) for continuously updating the created signature, and an abnormality detection module (26) for detecting abnormalities based upon deviations from the updated signature. The system may perform a method for detecting abnormalities occurring during a process based upon the continuously updated signature representative of the process. The method may include continuously monitoring a system parameter and computing a normal range of values for the system parameter based on the continuously updated signature. The method may additionally include determining if the monitored system parameter is within the normal range and indicating existence of an abnormality if the monitored system parameter is outside of the normal range.
Abstract:
Control of the self-testing of a plurality of elements (121 - 12m), each having a Built-In, Self-Test (BIST) capability, and arranged in one or more groups (141 - 14n), is carried out by a network (16) of one or more standard BIST resource interface controllers (SBRICs 181 - 18n). Each SBRIC in the network controls the self-testing of the elements in a separate one of the groups in sequence by broadcasting a test command to the elements in parallel which, in response, generate test signatures stored by the SBRIC. The SBRICs in the network are coupled in series in daisy chain fashion to enable the test signatures stored by the SBRICs to be concatenated for easy retrieval by shifting out the test signatures therefrom, using a technique such as boundary scan.
Abstract:
A data processing system comprising a plurality of computers interconnected through a local network, preferably in the form of a ring. The network being connected to a network adapter which is able to receive all information on the network. The network adaptor is connected to a computer which together with the adaptor can perform an assembling and scanning of substantially all files on the network and carry out a recognition of virus signatures. The individual file packets circulation in the network are assembled, said file packets being assembled in a file and scanned for virus signatures. When a virus signature is detected in the file, information is simultaneously provided on the transmitting stations and the receiving stations, whereafter it is possible to transmit the vaccine to the stations in question.
Abstract:
A testing methodology for very large scale integrated circuits, for example, microprocessors having several million transistors. Initially a set of pseudorandom test patterns is selected. During the design of the integrated circuit it is partitioned into functional units and each unit is designed to be verified and tested by the test patterns. During a test mode all of the units of the integrated circuit receives the test patterns in parallel. The output from each unit is coupled to a signature register. The contents of the signature registers are examined following application of the test pattern. This testing methodology lends itself to the simultaneous testing of many integrated circuits.
Abstract:
The present invention provides a system and method for self-testing and self-checking programmable logic. According to the preferred embodiment, a system is provided which includes a multiplexer having an output coupled to the input of programmable logic, and inputs coupled to normal input signal sources and a pseudo-random number generator. The multiplexer selectively couples an input to its output responsive to an input source signal. The output of the programmable logic is applied to normal output components and a data compression register which is controlled by a read enable signal. The system further includes a configuration control which independently generates the input select signal and the read enable signal.

Abstract:
Ein fehlertolerantes Datenverarbeitungssystem weist Gruppen (TMR) von gleiche binäre Datensignale liefernden und verarbeitenden Rechnereinheiten (SRU) und je eine logische Entscheidungseinheit (Voter) auf, welche über die Datensignale der Gruppe (TMR) abstimmt. Hiebei ist eine Mehrzahl von Gruppen (TMR) mit wenigstens drei, Datensignale liefernden oder verarbeitenden Rechnereinheiten (SRU) miteinander über Datenkanäle (K1, K2, K3) verbunden und die Voter einer Gruppe sind mit den Votern anderer Gruppen über Daten- bzw. Signalleitungen verbunden. Jede Datensignale liefernde oder verarbeitende Rechnereinheit (SRU) kann wenigstens einen Voter für die Entscheidung über die Fehlerfreiheit von Eingangs- und/oder Ausgangssignalen aufweisen. Zweckmäßig enthält jede Datensignale liefernde oder verarbeitende Rechnereinheit (SRU) einen Sequenzvoter für die Entscheidung über die korrekte Reihenfolge der zu verarbeitenden Signale.
