....requiring intensive arithmetic calculation on large numbers. The main drawback is that control logic can not be easily implemented because it mainly requires functional units on one bit. Another way to implement datapath structures is to change the design of the functional unit itself. In [6], 7] 8] for example, the functional unit is replaced by a reconfigurable ALU, combined with a special routing architecture. A similar approach can be found in [9] 10] and [11] where they are using multibit ALU. Even if these architectures support more complex operations, they are not well ....
