Abstract:
The invention relates to a method for distributed, fault-tolerant clock pulse generation in hardware systems, wherein the system clock pulse is generated in distribution by a plurality of intercommunicating fault-tolerant clock pulse synchronization algorithms (TS-Algs), in which an arbitrary number of such TS-Algs exchange information between one another via a user-defined and permanent network (TS-Net) of clock pulse signals, susceptible to transient faults, and each TS-Alg is assigned to one or more functional units (Fu1, Fu2, . . . ), whose local clock pulses are generated by it, and further all local clock pulses are synchronized with respect to frequency in an assured manner, and a specified number of transient and/or permanent faults may occur in the TS-Algs or in the TS-Net, without adversely affecting the clock pulse generation and/or the synchronization accuracy, and the system clock pulse automatically achieves the maximum possible frequency. The invention further relates to such a hardware system.
