What is the significance of carry-skip adder?

The carry-skip adder shortens the critical path by computing the group propagate signals for each carry chain and using this to skip over long carry ripples. The rectangles compute the bitwise propagate and generate signals, and also contain a 4-input AND gate for the propagate signal of the 4-bit group. The skip multiplexer selects the group carry-in if the group propagate is true or the ripple
adder carry-out otherwise.
