ARM Jazelle, is it on Beagle ?

Does the OMAP3530 on the Beagle Board support the Jazelle
execution environment and does anyone know if the Dalvik VM
can take utilize the Jazelle architecture ?

Don't know about the first question, but I'd guess that due to the
licensing status of Dalvik, the answer to the second question is 'no'.

b.g.

The Cortex-A8 in OMAP3 has Jazelle RCT which doesn't support
direct execution of JVM opcodes (which Jazelle DBX has; J variants
of ARM9 and 11 have Jazelle DBX). Jazelle RCT has some
additional functionality to help Java JIT.

Hi,
the spec tells you that the cortex a-8 has the simplest form of direct
execution: every bytecode triggers a piece of software which should
implement the code. Kinda like hardfloat without FPU.

IOW run a proper jit. Angstrom delivers (or can deliver) PhoneME
Advanced (CDC) and Cacao+Classpath (J2SE-like).

Well… The Dalvik VM doesn’t run “Java” bytecode, does it?
