ABSTRACT:
A logic circuit system, having a programmable logic circuit including a circuit configuration including a first set of plural unit circuits and that is reconfigurable during operation, a circuit configuration information supplier configured to supply circuit configuration information about a second set of plural unit circuits to said programmable logic circuit, a change controller configured to change the circuit configuration of said programmable logic circuit from said first set of said plural unit circuits to said second set of said plural unit circuits based on said circuit configuration information, an operation time measurer configured to measure operation times of said first and second set of plural unit circuits, and a clock-and-voltage supplier configured to use said measured operation times to change from a first frequency and voltage value corresponding to said first set to a second frequency and voltage value corresponding to said second set, and to supply a clock signal having said second frequency and voltage value to said programmable logic circuit, thereby varying a programmable logic circuit frequency and voltage value in accordance with variations in said operation times.
