Claim 8:
9. A method for synchronizing power states between a plurality of integrated circuit dies coupled together, the method comprising:
determining, by a first integrated circuit die of the plurality of integrated circuit dies, to synchronize a power state change of the plurality of integrated circuit dies from a first power state to a second power state, wherein the first and second integrated circuit dies include respective processor circuitry configured to retrieve program instructions from random access memory and execute the program instructions to implement software routines;
issuing, by the first integrated circuit die and to the second integrated circuit die, a request to transition from the first power state to the second power state;
receiving, by the first integrated circuit die and from the second integrated circuit die, an acknowledgement that the second integrated circuit die has transitioned to the second power state; and
transitioning, by the first integrated circuit die, the first integrated circuit die from the first power state to the second power state.
