Abstract: An integrated circuit includes logic regions and dynamically adjustable voltage controllers. A voltage controller connected to each logic region enables voltage adjustment while the chip is operating. Each voltage controller has a selector device connected to voltage input lines providing different voltages. A voltage sensor connected to the output of the selector device provides a supply voltage to one of the logic regions. A control circuit dynamically monitors the supply voltage, captures and stores a digital representation of the supply voltage during each cycle of a clock, and tracks variations over time, based on operation of the logic regions. When variations in the supply voltage exceed an operational threshold of one of the logic regions, the control circuit submits a request to a central controller. When the central controller grants permission, the control circuit dynamically adjusts the voltage by enabling the selector device to choose a different voltage input line.
