31. Assume we have a 16-bit Arithmetic Logic Unit. What will be the value of Result register if we are Remember: the ALU has three inputs and three outputs. The selection value will be (11)2 for Set on Less Than using the ALU to determine if X = 36.,0 32. Match the disadvantages with the appropriate adder: Long propagation delay Requires redundant hardware Each stage requires additional hardware a) b) c) Ripple-Carry Adder Carry-Select Adder Carry Lookahead Adder 1 2. 3. A) a1, b2, c3 B) a2, b1, c3 C) a3, b1, c2 D) a3, b2, c1 E) None
