Question:

For each of the calculations of Problem 6-28, determine if overflow has occurred.


Data from Problem 6-28

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

(a) A register = 1101 (-3), B register = 0011 (+3); SUB = 1, ADD = 0.

(b) A register = 1100 (-4), B register = 0010 (+2); SUB = 0, ADD = 1.

(c) A register = 1011 (-5), B register = 0100 (+4); SUB = 1, ADD = 0.
