Kaspar & Adam,
Thanks for the ideas (lejos and non-JVM langs). I am already in touch
with the lejos admin.
All,
An earlier suggestion was to investigate SOCs like Raspberry Pi or
BeaglBoard. At first I thought: OK this is exactly what I need! But now
that I'm really thinking about it, there's something that leaves me
feeling uneasy here.
So the main argument against the ARM SAM3X8E for a JVM is that it only
has 512KB ROM and 96KB RAM. But after researching the RaspberryPi, the
later models are using an ARM Cortex-A7 CPU that, according to Wikipedia
it has 1MB RAM. So this doesn't make sense: why is RaspberryPi touted as
a JVM-capable ARM-based SOC, whereas SAM3X8E is totally incapable of
such a feat (nothing in the modern Java landscape will run on 1MB).
Clearly I'm missing something here, but: what is the difference between
RapsberryPi's ARM processor vs SAM3X8E that makes it capable of running
a Java app?!?
Thanks,
Zac

When you're evaluating embedded JVMs, take a look at the VM used by
leJOS. It seems like it could rather easily be cut out of the OS,
and it
is apparently very capable even on the lego NXTs (64kb RAM, 256kB
flash), and seems like more than a research proof-of-concept.
