1. A method for conserving an amount of energy consumed by a processor, comprising the steps of:

supplying the processor with a predetermined supply voltage;

detecting a randomized signal, wherein the detected randomized signal is amplified to a predetermined level if the detected randomized signal is below the predetermined level; and

providing an output data bit having a logical value of a 1 or 0 from one or more switches in the processor according to a probability value that the output data bit is correct, the probability value being established in association with the randomized signal and the predetermined supply voltage, wherein an application executed by the processor uses the output data bit for one or more additional computations.
