Summary

The development of reliable software for real-time systems is currently a challenge. Moreover, changing the underlying platform for simple purposes such as a processor upgrade may severely affect the behavior of the real-time software. Working with distributed systems is even more difficult, and transitioning from one system to another is typically impossible.

We address these problems through a development framework for deterministic and portable real-time software using the Timing Definition Language (TDL). It enables transparent, yet deterministic distribution of real-time components regardless of the target platform and its deployment architecture. In this paper, we introduce the algorithms and internal mechanisms for transparent real-time distribution, and analyze the interactions between the user-functionality, the virtual machine of the language, the communication subsystem, and the underlying platform.
