Disclosed are various embodiments providing processing circuitry that generates an output for each clock cycle of a clock signal using a logic block, the logic block being powered by a supply voltage. The processing circuitry detects whether the output has stabilized at a point in time before the end of a clock cycle of the clock signal, the point in time being based at least upon a delay line. In response to detecting whether the output has stabilized at a point in time, the processing circuitry dynamically adjusts at least one of the supply voltage or the frequency of the clock signal.
