The present invention provides a method involving at least one first circuit having at least one first input, at least one second input, and at least one output. The method includes determining at least one first value of at least one output of a second circuit based on at least one first value of the at least one first input. The second circuit has been configured using first configuration information generated based on the first circuit and at least one first value of the at least one second input. The method also includes generating, concurrently with determining the at least one first value of said at least one output, second configuration information based on the first circuit and at least one second value of the at least one second input.
