The result of the following 8086 assembly language program is:

MOV AX, BB11H

MOV CX, 1122H

ADD AX, CX

HLT

Explanation:

8086 Assembly Language Program Analysis

Program:

MOV AX, BB11H
MOV CX, 1122H
ADD AX, CX
HLT

Let us analyze the given assembly language program step by step to determine the final values of the registers and the result of the program:

Step 1: MOV AX, BB11H

• This instruction moves the hexadecimal value BB11H into the register AX.
• After execution, the value of AX will be BB11H.

Step 2: MOV CX, 1122H

• This instruction moves the hexadecimal value 1122H into the register CX.
• After execution, the value of CX will be 1122H.

Step 3: ADD AX, CX

• This instruction adds the value of the register CX to the value of the register AX and stores the result in AX.
• Performing the addition in hexadecimal:
• AX = BB11H
• CX = 1122H
• AX + CX = BB11H + 1122H = CC33H
• After execution, the value of AX will be CC33H.

Step 4: HLT

• This is the Halt instruction, which stops the execution of the program.
• At this point, the values of the registers are as follows:
• AX = CC33H
• CX = 1122H

Final Result:

The final value of the register AX after the execution of the program is CC33H.

Correct Option: Option 2: AX = CC33H

Important Information

To further understand the analysis, let’s evaluate the other options:

Option 1: CX = BB11H

This option is incorrect because the register CX is explicitly loaded with the value 1122H during the execution of the program. The value BB11H is loaded into the register AX, not CX.

Option 3: AX = BB11H

This option is incorrect because while the value of AX is initially set to BB11H, it is later updated to CC33H after the addition operation with the value of CX (1122H).

Option 4: CX = CC33H

This option is incorrect because the value of CX is not modified during the program. It remains 1122H throughout the execution. The value CC33H is the result stored in AX after the addition operation.

Option 5: (Blank)

Since no fifth option is provided, it is not relevant to the analysis.

Conclusion:

The program involves basic assembly language instructions for moving data and performing addition in the 8086 microprocessor. The correct final value of the register AX after executing all instructions is CC33H, making Option 2 the correct answer. The other options either misrepresent the values of the registers or fail to account for the operations performed during the program's execution.
