Consider the following two 8-bit binary numbers A and B: A=0100 0000 B= 1101 0000 1. Assume that A and B are two unsigned binary numbers and an 8-bit unsigned adder/subtractor is used a) Give a convincing reason why or why not there will be an overflow when adding these two numbers (A+B). b) Give a convincing reason why or why not there will be an overflow when subtracting these two numbers (A-B). 2. Assume that A and B are two 2's complement signed binary numbers and an 8-bit signed adder/subtractor is used a) Give a convincing reason why or why not there will be an overflow when adding these two numbers (A+B). b) Give a convincing reason why or why not there will be an overflow when subtracting these two numbers (A-B)
