It's in my syllabus but there's no mention of it in my book. Can someone explain to me what is a Carry Propagate Adder?

They're probably using the term to distinguish a standard ripple carry architecture from a "carry look-ahead adder." The look-ahead system is a way to calculate the carry without waiting for it to ripple through a full adder chain.
