Abstract:
A system and method are provided for supplying bulk current to a voltage regulator embedded on a system-on-chip (SoC). An embedded voltage regulator (EVR) supplies a regulated voltage to a functional unit, the current demand is determined, and a current control signal is generated. An off-SoC bulk current source accepts the current control signal and supplies auxiliary (bulk) current to the functional unit in response to the current control signal. For example, in a first period of time a dynamic increase demand for a first current. Initially the EVR supplies the first current and creates an increase in SoC thermal loading. Subsequently, the EVR supplies a current less than the first current while the bulk current source supplies the bulk of the current. As a result, the bulk current source creates an off-SoC thermal load.

Claim (Index 1):
A composite embedded voltage regulator (CEVR) comprising:\n a system-on-chip (SoC) comprising:\n a single substrate having a maintenance power interface; \n a functional unit formed on the substrate, having an input supply to accept power; \n an embedded voltage regulator (EVR) formed on the substrate, having an input supply connected to the maintenance power interface to accept a voltage, and having an output supply connected to the functional unit input supply to provide a regulated voltage; \n a bulk current interface connected to the functional unit input supply; \n a bulk current source having a control input to accept a current control signal responsive to the functional unit current demand, and an output supply connected to the SoC bulk current interface to only supply current to the functional unit input supply when enabled in response to the current control signal; wherein the functional unit, in a first period of time, creates a dynamic increase demand for a first current; in an initial portion of the first period of time, the EVR supplying the first current; and, in a subsequent portion of the first period of time:\n the EVR supplying a second current less than the first current; \n the bulk current source supplying a third current equal to the first current minus the second current; \n wherein the functional unit, in a second period of time following the first period of time, creates a dynamic decrease demand for a fourth current, less than the third current; wherein the EVR supplies the fourth current in the second period of time; and, wherein the bulk current source ceases to supply current in the second period of time.
