1. An integrated circuit (IC) comprising:

  • a first logic circuit;

    a second logic circuit; and

    a storage circuit connecting an output of the first logic circuit and an input of the second configurable logic circuit, wherein;

    at a first clock cycle, the storage circuit is open to allow a particular signal to propagate from the output of the first logic circuit to the input of the second logic circuit for performing a particular logic operation; and

    at a second clock cycle, the storage circuit is closed to hold the particular signal to allow the second logic circuit to continue to perform said particular logic operation.
