1. A computing system comprising:

  • a synchronous circuit including 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;

    an error detector operable to detect an incidence of a computational error occurring in the first subcircuit; and

    a controller operable to change the first power plane voltage based upon the detected incidence of a computational error.
