2. [6 marks] Unsigned and signed arithmetic operations and overflow For a. below, convert each of the operands (unsigned decimal values) into its corresponding binary value (w = 8). For b. below, convert each of the operands (signed decimal values) into its corresponding two's complement binary value (w = 8). For a. and b. below, perform both the decimal addition and the binary addition and indicate the true sum and the actual sum and whether they are the same or different. For the binary addition, clearly label all carry in bits (by using the label "carry in") and the carry out bit (by using the label "carry out"). Finally, indicate whether or not an overflow occurred (for signed values, specify whether the overflow is positive or negative). If an overflow occurred, explain how addition overflow can be detected ... 1. at the bit level, and 2. using the decimal operands. b. Signed (two's complement) addition: I. 2810 + -7410 II. -117 10+ 12610 7410 + 6310 IV. -11910 + -10510
