- How to obtain data of the realtime capability of a stateoftheart computer system?
To determine whether a given system (hardware, firmware and software) is deterministic with respect to a given response deadline is much more difficult now than it was in earlier days. Until 10 to 20 years ago, the worstcase latency of a system could be determined theoretically: Using the socalled path analysis, the longest critical section that ever could be encountered in a system was determined, and the processor cycles required by the instructions of this section were then multiplied with the cycle duration.
