Patent ID: 8392745

Claim:
A modular integrated circuit comprising: a plurality of spoke modules; and a plurality of hub interfaces, each of the plurality of hub modules coupled to a corresponding one of the plurality of spoke modules to provide a signal interface; a hub module that is coupled to the plurality of spoke modules via a non-bus architecture that facilitates inter-spoke communication via the hub and the plurality of hub interfaces, the hub module including: a memory module, coupled to the plurality of hub interfaces, that stores hub software and hub data; a power management unit, coupled to the plurality of hub interfaces, that selectively supplies a plurality of power supply signals to the plurality of spoke modules via the plurality of hub interfaces; and a clock control circuit, coupled to the plurality of hub interfaces, that selectively supplies a plurality of clock signals to the plurality of spoke modules by: receiving a clock request signal from a corresponding one of the plurality of spoke modules via the signal interface of the corresponding one of the plurality of hub interfaces; generating at least one of the plurality of clock signals in response to the clock request signal; and sending the at least one of the plurality of clock signals to the corresponding one of the plurality of spoke modules via the signal interface of the corresponding one of the plurality of hub interfaces.
