Question 3: Overflow in Two's Complement Compute if the following operations overflow in 5-bit two's complement. For the answer, provide the carry bits, whether there is an overflow, and the decimal equivalent operation 1. 01000 – 11000 Result and carry bits: Does it overflow? Decimal version: 2. 10000 + 01111 Result and carry bits: Does it overflow? Decimal version:

1) Assume we have a 2's complement system with an 8-bit whole number part and a 2-bit fractional part. Find a decimal representation of 2's complements binary number 1110 0010.01 2) Assume we have 16-bit (2 bytes) 2's complement system with a 2-bit fractional. Find a decimal representation of 2's complements number 1111 1111 1110 0111.11
In this question, you are provided with two unsigned binary numbers, A and B. You are asked to evaluate (-A - B) as well as (-A+B) using the two's complement 12-bit number system. If the result is encoded in less than 12 bits (including the sign bit), you need to extend it to fill the entire 12 bits. Indicate if an overflow occurred or not. N.B.: You need to provide the entire 12-bit result, even if an overflow occurs. You MUST report the answer in 2's complement. Do NOT convert the number back from the 2's complement. Leave it in the 2's complement representation. When A = 10110011010 and B = 100111100, the value of (-A - B) = the value of (-A + B) = If an overflow occurred during evaluating this expression, type yes, if not type no If an overflow occurred during evaluating this expression, type yes, if not type no = ; and

Subtract the following two 8-bit binary numbers (use 2's complement): 00011010 - 00001010 First, determine the two's complement of 00001010: Blank #1 Next, add 011010 and the two's complement of 00001010: Blank #2 How many times did you need to carry? Blank # 3 Given that the result is stored in an 8-bit register, is there overflow (Y/N)? Blank # 4
Is the following a valid alternative definition of overflow in twos complement arithmetic? If the exclusive-OR of the carry bits into and out of the leftmost column is 1, then there is an overflow condition. Otherwise, there is not.

Calculate the parity of a byte with the value 31 and show the pattern stored to memory. Assume the parity bit is on the right. Suppose the most significant bit was inverted in memory, and then you read it back. Did you detect the error? What happens if the two most significant bits are inverted?
Perform the following additions, assuming 7-bit two's complement binary representation. Show the effect on the status bits (NZVC). Example: Example: Note: that this is a 6-bit example and the questions below are for 7-bit. ex) 101000 + 100000 001000 NZVC 0011 Result was 1001000 but the 1 is carry-out (C-1). Negat ive + Negative should be Negative but positive so overflow (V=1) a) NZVC b) NZVC 1101001 + 1110001 1111111 + 0110101
