The Ericsson AXE-based systems are programmed using an internally developed language called Plex-C. Plex-C is normally compiled to execute on an Ericsson internal processor architecture. A transition to standard processors is currently in progress. This makes it interesting to examine if Plex-C can be compiled to execute on the JVM, which would make it processor independent. The purpose of the thesis is to examine if parts of the run-time environment of Plex-C can be translated to Java and if this can be done so that sufficient performance is obtained. It includes how language constructions in Plex-C can be translated to Java. The thesis describes how a limited part of the Plex-C run-time environment is implemented in Java. Optimizations are an important part of the implementation. It is also described how the JVM system was tested with a benchmark test. The test results indicate that the implemented system is a few times faster than the Ericsson internal processor architecture. But this performance is still not sufficient for the JVM system to be an interesting repla...
