Very Computer

I am researching hardware for a project that has the following primary
requirements:

1. low-power consumption
2. min. 2 serial ports, Ethernet port
3. capable of running a Java 2 JVM (and I mean running - not crawling ;-))
4. capaple of running an embedded DB (Java) system
5. low cost

I had a good search at the archives but most of the suggestions seem to be
'cutting edge' type hardware - which in most cases means high cost . I would
rather go for some established hardware as my computing requirements are not
that high.

The software that the system is going to run is very networking heavy
(XML-RPC ...) but no GUI or Graphics stuff. The system is going to run more
or less headless.

Size of the system is not a big issue. System is going pretty much
stationary.

Since my background is more software heavy I would like to get some feedback
what hardware is being used out there for similar projects.

Thanks in advance,

May I suggest that you investigate the following

Thanks Dennis,

I hava actually looked at LART pretty closely. I am having trouble finding a
supplier that can supply these. The only one I found (in the UK) is totally
out of stock. I think it would be hard to commit to a hardware platform
without stable supply.

Any suggestions for other suppliers

Leo

Ummm... do you need any floating point calculations?

If you don't need to perform a lot of FP calculations you should have
a look at the MPC8xx PowerPC systems; they have a on-chip communi-
cations processor which allows good network performance with minimal
impact on the CPU. The TQM8xxL modules are something that matches
your requirements (up to 64 MB RAM, 8 MB flash, 2 x RS232, Ethernet /
Fast Ethernet and more on a board half the size of a credit card;
total power consumption < 2 Watts [worst case]; Linux enabled [Linux
already installed in flash when you get the system]).

See http://www.denx.de/embedded-ppc-en.html for some images.

Feel free to contact me for more details, prices, etc.
