    摘要: A communication system which consists of several modules—operating in parallel on segments of a packet—to increase speed and handling capacity. One module acts as master, the others are slave modules controlled by control signals derived by the master module. It is important that in each module the data segment and the respective control signal of each packet are correctly synchronized, because in large systems the data paths carrying packet segments and the control signal paths may have substantially different delays. The invention provides for measurement of the propagation delay differences and for introducing a controlled delay in each slave module, so that data segments and control signals can be correctly correlated by delaying either the one or the other. Synchronization packets are transmitted besides normal data packets, for obtaining time stamps which are used to determine the delay difference.

    摘要: For switching or transmitting data packets, one can provide communication systems which consist of several modules —operating in parallel on segments of a packet —to increase speed and handling capacity. One module acts as master, others are slave modules controlled by control signals derived by the master module. It is important to correctly synchronize in each module the data segment and the respective control signal of each packet, because in large systems the data paths carrying packet segments and the control signal paths may have substantially different delays. The invention provides for measurement of the propagation delay differences and for introducing a controlled delay in each slave module, so that data segments and control signals can be correctly correlated by delaying either the one or the other. Synchronization packets are transmitted besides normal data packets, for obtaining time stamps which are used to determine the delay difference.

    摘要: The present invention relates to a method and system for testing error detection programs dedicated for detecting hardware failures in a computer system, in which error case patterns comprising stimuli values are generated and response patterns to the hardware are evaluated. In order to develop and debug such error detection programs already at an early phase during hardware development it is proposed to feed a simulation model (26) of said hardware with said error patterns, and after running said model, evaluating (12) the model response patterns generated by the simulation model and comparing the response patterns with those expected as a result of the error detection program.

The output or contents of one cell can be connected to another cell to alter the logic operation of the second cell even while this second cell is in operation. The cells can be connected together to form a neural network.
