Measuring the performance of real-time systems

So far, performance measures for real time systems did not receive much att ention. An assessment of the few existing benchmarking methods for real tim e systems will reveal that they are highly inappropriate. Taking a closer l ook into the fundamental issues of real time systems it will become clear, that for hard real time systems qualitative characteristics are much more i mportant than quantitative measures. The major qualitative performance crit eria are compiled. Systems fulfiling the qualitative aspects may then be co mpared on the basis of costs.
