Claim 7:
8. A method comprising:
receiving, by circuitry of a control unit, register accesses from at least a first initiator in a first semiconductor die of a plurality of semiconductor dies and, via a communication link, register accesses from at least a second initiator in a second semiconductor die of the plurality of semiconductor dies;
in response to receiving a given register access, determining which copy of a targeted register to access so as to fulfill the given register access;
performing the given register access to a first copy of the targeted register responsive to determining the first initiator generated the given register access; and
performing the given register access to a second copy of the targeted register responsive to determining the second initiator generated the given register access, wherein the second copy is different from the first copy.
