Thanks!
I read that link. That's too bad as that would have been exactly what I wanted
if the "core" was anything close to C or Python.
I believe that opencores has a SystemC description of an ARM somewhere
on the site. You might want to poke around.
If you want models for processor cores, www.opencores.org is probably
the best place to start. However, I'm not sure it's going to really do
what you want.
Additionally, you might want to consider the skyeye emulator. It seems
to emulate some ARM stuff reasonably well.
Is it possible to take an emulator in a general purpose language like Skyeye
and convert that to a hardware realization?
In general, no. There are things like SystemC and MyHDL that add/limit
the language to a "synthesizable subset", but most simulators/emulators
don't bother.
Now, VHDL has some relation to the old versions of Ada, so that might be
considered a "general purpose" language if you know Ada.
If you really are willing to put the work into ARM emulators, skyeye
would be my first choice to look at. My second choice would be
"desmume" which is a Nintendo DS emulator. The Nintendo DS has both an
ARM7 *and* and ARM9 core. Desmume emulates both.
Or, coming from the opposite end, is it possible to convert these opencores.org
specs into something I'll understand like C or Python?
Probably not without an amount of work that would be equivalent to
writing it yourself. Also, define "understand".
If you really want to give that a shot, go look at MyHDL. It's a set of
modules for Python that uses generators, decorators and some judicious
classes to add HDL capabilities into Python.
It includes its own simulation engine.
