Method and system for the continuous preparation of a präzisionssystemakts

摘要

The present invention relates to a process for the continuous preparation of a precision of the system clock, of a processor core (2) is associated, wherein the system clock a host - clock register (5) comprises, by means of a precision oscillator is updated the process comprises the steps of providing a firmware - clock register (6), the incrementing of the firmware - clock register (6) in the case of each of the host - clock register (5), the monitoring of precipitation of the host - clock register (5) and in the case of a failure of the host - clock register (5) the continuous counting-up of the firmware - clock register (6) with the aid of time signals of the processor core (2) as well as in the case of receiving a request to provide a clock value the providing of the contents of the host - clock register (5), if no failure has been detected, and otherwise the contents of the firmware - clock register (6).
