Question:

For each of the calculations of Problem 6-27, determine if overflow has occurred.


Data from Problem 6-27

For the circuit of Figure 6-14, determine the sum outputs for the following cases.

(a) A register = 0101 (+5), B register = 1110 (–2); SUB = 1, ADD = 0 

(b) A register = 1100 (–4), B register = 1110(–2); SUB= 0,ADD = 1 

(c) Repeat (b) with ADD = SUB = 0.
