Detailed Description

Multiple Adder: adds many input words in cascade.

This multi-sage adder works in cascade, adding 2^N numbers together, where N is the number of stages. The minimum latency of the block is N clock cycles (being N the number of stages) A delay might be added to synchronise with outher adders, multipliers, etc.. The total latency is L = N + D clock cycles, where N is the number of stages and D is the delay.
