Abstract:
1. A method of delivering power to an integrated circuit comprising functional blocks, the method comprising: providing a first power source to a first functional block of the integrated circuit for supporting a first operating mode of the first functional block; deriving a second power source from the first power source; and providing the second power source to the first functional block for supporting a second operating mode of the first functional block; operating the first functional block in the first operating mode for a first time period; and operating the first functional block in the second operating mode for a second time period, wherein the first time period and the second time period are determined based on a desired average throughput for the integrated circuit, and wherein the first power source is a shared high voltage rail coupled to a high voltage source outside the integrated circuit, and the second power source comprises a first on-die voltage regulator coupled to the first functional block and wherein the first on-die voltage regulator is integrated on a same die as the integrated circuit.
