Logic Instructions Answer the question for each set of assembly codes. Answer in hexadecimal format. 1. MOV AX, 614BH MOV BX, 1251h What would be the value of AX after program execution? AND AX, BX RET 2. MOV AX, 614Bh MOV BX, 1251h OR AX, BX What would be the value of AX after program execution? RET 3. MOV AX, 614BH What would be the value of BX MOV BX, 1251h after program execution? XOR BX, AX RET 4. MOV DX, 614BH What would be the value of DX NOT DX after program execution? RET 5. MOV AX, 614BH MOV BX, 1251h What would be the value of AX after program execution? AND AX, BX NOT BX XOR AX, BX RET

The following one-operand instructions (Accumulator machine with single register AC) are corresponding to the arithmetic expressing: Load D Sub C Store T Load B Add A Div T Store Y Select one: O a. Y = (C-D)/(A+B) O b. Y= (D-C)/(A+B) O c. Y= (A+B)/(D-C) O d. Y= (A+B)/(C-D)

(b) Construct a sequence of instructions such that (i) you add the 8- digit BCD number in AX and BX to the 8-digit BCD number in CX and DX. (AX and CX are the most significant registers. The result must be found in CX and DX after the addition.). (ii) Then logically shift AX right by 12 bit positions and the rightmost 12 bits of BX into the leftmost 12 bits of AX using double precision shifting. (iii) Assuming that DL= 0F3H and BH=72H , compute the answer after BH is subtracted from DL and show the contents of the flag register bit
