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.
