Re: 'virtual HW' into kernel (SystemC)

[Màrius Montón <Marius.Monton@uab.es>]

All suggestions are good, but from my point of view, both solutions
(entire simulated system, or using an emulator) could be too slow and
too much artificial, so in translation to 'real world' can be a lot of
problems.

I think our approach is the most real environment for our SystemC module.

We will try to implement in this way, so any hints here will be appreciated.
Thanks

Màrius
