SystemJ is a language based on the Globally Asynchronous Locally Synchronous (GALS) paradigm. A SystemJ program is a collection of GALS nodes, also called clock domains, and each clock domain is a synchronous program that extends the Java language. Initial compilation of SystemJ has been to standard Java executing on a Java Virtual Machine (JVM), which is both inefficient and bulky for small embedded systems. This article proposes a new approach for compiling and executing SystemJ using a new type of virtual machine, called a Tandem Virtual Machine (TVM). The TVM approach provides an efficient implementation of SystemJ on both standard processors and resource-constrained embedded processors. The new approach is based on separating the control-driven and data-driven operations for execution on two virtual machines. While the JVM executes the data-driven operations, a Control Virtual Machine (CVM) is introduced to execute the control-driven parts of a SystemJ program. The TVM approach is capable of handling all data-driven and control-driven operations required by the GALS model. The benchmark results show that the TVM has code size improvements of over 60% on average and also a substantial improvement in execution speed over standard Java-based compilation.
