QUESTION
A 16-bit ALU is built up of 16 1-bit ALUs, each one having an add time of 10 nsec.
A 16-bit ALU is built up of 16 1-bit ALUs, each one having an add time of 10 nsec. If there is an additional 1-nsec delay for propagation from one ALU to the next, how long does it take for the result of a 16-bit add to appear? Explain your answer.
