Jet is one of the cornerstone of Avalpa value proposition; it's a middleware for interactive digital set top box.

It's based on phoneme, the java virtual machine that Sun Microsystems released in december 2006 as GPL licensed software. Jet is actually using the PowerPc porting of the phoneme vm.

Anyway, we recently started to evaluate, both technically and economically, the porting of Jet to a high definition System on Chip (SOC) like the StMicroelectronic STi710x. (thankx to them for a great linux support and SDK)

As a successful first proof of concept, as of today 29.7.2009, we are releasing the missing files to have latest phoneme svn compile and execute succesfully on the SH4 cpu.

Remeber, this is of course a beta version software and should be used "as is" for sampling purposes only.

Currently the build is successfully tested against foundation tests classes, see here the printed results:

Here the results of the Caffeine Embedded 3.0 benchmark:

root@boxhd# bin/cvm -cp embed.zip CaffeineMarkEmbeddedApp
Sieve score = 210 (98)
Loop score = 237 (2017)
Logic score = 226 (0)
String score = 1065 (708)
Float score = 203 (185)
Method score = 224 (166650)
Overall score = 285

and also some more complex software (not so useful for interactive tv!) like rhino (a javascript interpreter for java) and jetty a java web server.

Hello SimpleServlet

we want to share our current results with others people from the community to test and improve together this effort...

Pick up an account if you don't have already one and head on to the reserved area to download the tarball with some easy instruction inside.

Beware, if you really want to test this stuff, you should have a friendly STB with a STi710x SOC inside and be really acquainted with:

• the java latest SDK
• the STLinux SDK
• the phoneme buil process

Have fun and enjoy.
