I'm currently searching for a Java VM which is portable (or already ported) to an ARM Cortex M3 (LPC1768 from NXP, 512kB ROM ). I have already some experience with simple Real Time Java (www.rtjcom.com) which has a small footprint and is well documented. Do you know some more embedded JVMs for Cortex M3? Ideally with a real Byte Code interpreter and a ClassLoader?
Thanks for your suggenstions.
The following a Java VMs target embedded systems:
- JamaicaVm (Commercial)
- MicroJVM (Comercial)
- Aonix Perc (Commercial)
- PreonVm (Commercial)
- AvianVM (Open source)
- Open Mika (Open source)
- Squawk (Open source)
- SimplRJT (Open source needs no RTOS for threading support - seems to have disappeared)
- Kaffe (Open source).
This article by Michael Barr and Jason Steinhorn may also be helpful.
Note that on a Cortex M3 it may be very slow. An ARM part with Jazelle or ThumbEE may be more appropriate.
Take a look at IS2T JVM as well, as the other JVM simply do not run on Cortex M devices.
