1. A method for using a data path comprising a plurality of processing elements (PEs), the method comprising the steps of: transmitting at least one carry bit from a first PE to a second PE using a left-going carry chain; generating at least one signal in the second PE in response to the received carry bit; and transmitting the at least one signal from the second PE to the first PE using a right-going carry chain, wherein the at least one signal reconfigures the data path.
