i need to model the on board cpu of a satellite in order to
mock running uploaded commands. basically i need to model
the internal state and all incoming commands so i can
determine register states at a given point in time.
Not to distract the thread from your very real question, but you do
realize that you have one of the coolest jobs around, right?

Right, why should we help him hey?
Seriously Ara wasn’t there a Ruby Q. about it http://rubyquiz.com/quiz88.html
(the only one I replied to BTW)?

The last processor I successfully modeled was the old 6502 (Apple II),
since
then processor behavior has become too difficult to sort out in any
reliable way (IMHO).
It would be interesting for the OP to reveal what kind of processor is
involved, and how complex. I am going to assume it doesn’t support
interrupts or threads, otherwise there is little chance to mimic its
behavior.

at this point i only need to model a limited subset of the processor (i
don’t
know the type yet). basically i’ll be executing something long these
lines
as you can tell these are load/store/add instuctions. there are no
parameters, all the values are burned on board before flight - so there
are
only certain values you can do ops with. as you can tell it’s ultra
simple -
basically i’ll just have to model rom, ram, registes, and ops.

Isn’t there an open-source “universal old architecture emulator” package
of some kind? I remember seeing it in Debian when I was running Debian
– it could play most of the old Atari games, etc.
I can certainly see if it’s in Gentoo, if I can figure out what it was
called.
