Abstract
The present invention is an incrementor that receives as inputs a 32-dit 1-of-4 operand and a 1-of-2 increment control signal. For each dit of the operand, the present invention determines whether the increment control signal, which is treated as a carry into the least significant dit, propagates into said dit. If so, the value of the dit is incremented. Otherwise, the dit value is output without modification. The present invention also generates a carry out signal if the increment control signal has propagated across all dits.
