A stacked module device and corresponding module and method are provided
where at least some modules have input ports connected to receive first
resource related signals and output ports connected to provide second
resource related signals. The first and second signals are different, and
each module comprises a resource signal transformation unit for
generating the second signal from the first signals. The resource signal
transformation units of each module are of the same construction.
