Perform the following addition of word size numbers. Give the sum in hex as a word size number. State whether or not overflow occurs. State whether or not there is a carry. Check each answer by converting the problem to both decimal interpretations (unsigned and 2's complement); show that the unsigned interpretation is correct when there is no carry, and the signed interpretation is correct when there is no overflow. (15 points) 0387 +3FDC Suppose you have a "binary clock," the display of which is an array of LEDs where the first two columns give the 10s and 1s digits of the hour, the next two columns give the minutes and the last two give the seconds, each in binary where a lit LED means 1 and an unlit LED means O. Identify the time shown on the clock display below. (10 points) 0 0 Perform the following addition of word size numbers. Give the sum in hex as a word size number.
