Description

Comment lifted from discussion in the pret-noc paper:

Currently I believe that ''blocking'' means that the hardware
continues as usual, except for the fact that future usages of the NoC will
silently fail because the NoC is stuck in this ``blocking'' state. Why do we do
this?

The blocking state seems useless to me. I am not sure about the other states, but if we could get rid of them then that could make concurrent accesses to the NoC by different threads on the same core less complicated.
