Abstract
Embodiments include a system, a device, and a method. A computing system includes a synchronous circuit. The synchronous circuit includes a first subcircuit powered by a first power plane having a first power plane voltage and a second subcircuit powered by a second power plane having a second power plane voltage. The system also includes an error detector operable to detect an incidence of a computational error occurring in the first subcircuit. The system further includes a controller operable to change the first power plane voltage based upon the detected incidence of a computational error. The system may include a power supply operable to provide a selected one of at least two voltages to the first power plane in response to the controller.
