Modeling a simple cpu

Ruby
1

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.
has anyone out there done something similar? and helpful libs?
basically
i’ll need something like

dmsp_cpu = cpu{
register ‘oax’
register ‘oal’

 mem 0x55, :value => 0x2a39

 instruction 'oaxload' do |value|
   oax[ value ]
 end

}

etc.

regards.

What platform? What’s the type of cpu? I think Solaris/Sparc comes
with something that will let you do this.

You might want take a look at RHDL ( http://rhdl.rubyforge.org )
