Implement the logic function in Table by using 74HC151-Multiplexer. TABLE 6–10 MUX EN Decimal Inputs Output Digit Аз Ар A1 Ao Y A1 1 1 1 2 1 1 A2 3 1 1 A3 2 4 1 1 1 1 Ao 6 1 1 1 7 1 1 1 1 1 Y 8 1 1 2 9 1 1 10 1 1 1 3 11 1 1 1 12 1 1 1 4 13 1 1 1 1 5 14 1 1 15 1 1 1 1 1 6. 7 74HC151

6- Set BX to 4567H, CX to FEDCH and SP to A59FH, then run the instructions: PUSH BX PUSH CX a. What is the new value of SP ? b. Display the memory locations where you pushed the values of BX and CX in the stack.

a) 13–9 b) –13 –13 Perform the above decimal arithmetic problems by first converting the numbers to binary, 2’s complement form (using a 7 bit word in every case). Then perform the 2’s compliment addition. Show the result in binary indicating as in the problem above whether each result is positive or negative or overflowed (by writing “positive”, “negative” or “overflow” next to the binary answer) and then follow with the decimal value of the result if there was no overflow.
