Analysis and Simulation of Real-Time Systems

In the Further section we discussed a group of dynamic attributes which cannot be divorced from the functional needs of a real-time system:

•    Context switching, Interrupt handling
•    Response time
•    Throughput, Data transfer rate
•    Priority handling, Resource allocation
•    Inter task communication, Task synchronization

Each and every of these performance attributes can be specified but it is very hard to verify whether system parts will  achieve desired response system resources will  be  sufficient to  satisfy  computational needs or processing algorithms will execute with enough speed.

The analysis of real-time systems needs simulation and modeling which enables the system engineer to assess timing and sizing issues. While a number of analysis methods have been proposed in the literature example for [LIU90], [WIL90] and [ZUC89]), it is fair to state which analytical approaches for the design and analysis of real-time systems are still in their previously stages of development.
