Real Java for Real Time -- Gain and Pain
(2002) International Conference on Compilers, Architecture and Synthesis for Embedded Systems p.304-311- Abstract
- The Java programming language, being a portable and safe object-oriented language, has gained much interest among embedded and real-time systems developers. However, standard Java implementations exhibit problems with performance, memory footprint, and predictability. The question is then, are these limitations inherent in the technology?
Reviewing run-time aspects and the possibility to compile Java to native code, reveals some real limitations as well as common misconceptions. Investigation of the real limitations shows that for implementing real-time Java on small embedded platforms, native compilation via C is an appropriate solution for many platforms and applications.

However, standard Java implementations exhibit problems with performance, memory footprint, and predictability. The question is then, are these limitations inherent in the technology?
Reviewing run-time aspects and the possibility to compile Java to native code, reveals some real limitations as well as common misconceptions. Investigation of the real limitations shows that for implementing real-time Java on small embedded platforms, native compilation via C is an appropriate solution for many platforms and applications.
A revised technique for Java-compatible memory management is proposed to reduce latencies, and linkage of externally generated (C) code with natively compiled Java is considered in a prototype that has been implemented. Based on application demands and experimental verification, we find that real-time Java can, and should, retain the standard simple Java memory model to the programmer. (Less)
