Abstract :
We present a digit-serial architecture for gray-scale morphological operations which operates on radix-2 redundant numbers. We present new implementations of a redundant number adder and maximum unit used in the morphological dilation unit. These new designs have areas comparable to 2´s complement implementations, but have significantly smaller latencies
