Claim 0:
1. An apparatus comprising:
a first control unit in a first semiconductor die of a plurality of semiconductor dies, wherein the first control unit comprises circuitry configured to:
receive register accesses from at least a first initiator in the first semiconductor die 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, determine which copy of a targeted register to access so as to fulfill the given register access;
perform the given register access to a first copy of the targeted register responsive to determining the first initiator generated the given register access; and
perform 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.
