Re: Summary of minor issues

Hiroshi-san,

I'm not sure I understand your point. The SystemC standard has never
included ports for access to mutexes and semaphores, and this proposed
change does not affect that. The only change is that the base class of
sc_mutex/semaphore themselves will become sc_object instead of
sc_prim_channel, which gives more flexibility when instantiating these
objects. This change would NOT be backward-compatible if any existing code
exploits the fact that they are primitive channels (by using the
request-update mechanism), but that seems unlikely.

Regards,

John A

In our understanding, this change makes modules enable to access
sc_mutex and sc_semaphor without through sc_port. Is it correct?
We are wondering that this change may have negative influence on
interoperability of user models. Any comments?
