Nope, Bicore's technicaly only opperate in saturated state. What saturated
state means that the most number of processes in the loop are active, in
even numbered nv loops the number of pulses in staturated state are equal to
half the number of physical nv's. Think of a 4nv microcore, when a microcore
powers up, it powers up in saturated state. That means that at any one time
in this microcore, there are 2 nv's 'on', and two 'off'. In a 6 nv microcore
there are 3 nv's 'on' and 3 nv's 'off' at any one time. The PNC is used to
reduce this number to fewer pulses. For example, for the proper walking gait
in a 4nv walker, you need one pulse, not two. So the PNC gets rid of one. In
a bicore the saturated state IS the state that you want to use, so you don't
need a pNC to control it.
