  • Publication number: 20150200667
    Abstract: Provided are systems and methods for reducing power consumption in the interface and routing circuitry associated with various core modules of an integrated circuit or system. One system includes core modules, glue logic domains adapted to interface the plurality of core modules, and a power controller electrically coupled to the glue logic domains. Each glue logic domain includes a glue logic module implemented as a soft macro with metal traces extending beyond an extent of the glue logic module. The power controller decouples power from selected glue logic domains based on control signals and/or detected power down states of core modules and/or other glue logic domains. The power controller facilitates the power transitions using logic state retention, logic state clamping, ordered or scheduled transitioning, and/or other power transition systems and methods.
