Abstract
Full adder, a chip and a computing device are disclosed. A full adder includes: a plurality of primary logic cells and at least one secondary logic cell, wherein an output terminal of each primary logic cell is at least connected to an input terminal of a first secondary logic cell in the at least one secondary logic cell. The plurality of primary logic cells includes: a first primary logic cell, a second primary logic cell and a third primary logic cell respectively configured to generate a first intermediate signal, a second intermediate signal and a carry-related signal based on a first input signal, a second input signal and a carry input signal input to the full adder. Furthermore, the first secondary logic cell is configured to generate a sum output signal of the full adder based on the first intermediate signal, the second intermediate signal and the carry-related signal.
