Mathematical function performed by the following instructions:MVI A, 0...
Mathematical function performed by the following instructions:
The given instructions are:
1. MVI A, 07H
2. RLC
3. MOV B, A
4. RLC
5. RLC
6. ADD B
Explanation:
Let's analyze each instruction and its effect on the mathematical function performed:
1. MVI A, 07H: This instruction loads the accumulator (A) with the value 07H. The accumulator is an 8-bit register used for arithmetic and logical operations.
2. RLC: This instruction rotates the contents of the accumulator left through the carry. The leftmost bit is shifted into the carry flag, and the carry flag is shifted into the rightmost bit. This effectively multiplies the contents of the accumulator by 2.
3. MOV B, A: This instruction copies the contents of the accumulator to register B. Register B is also an 8-bit register.
4. RLC: This instruction rotates the contents of the accumulator left through the carry again, performing a multiplication by 2.
5. RLC: Similarly, this instruction performs another left rotation through the carry, multiplying the contents of the accumulator by 2 again.
6. ADD B: This instruction adds the contents of register B to the accumulator. Since register B holds the original contents of the accumulator (before multiplication), this effectively performs a multiplication by 10.
Conclusion:
The mathematical function performed by the given instructions is the multiplication of the content of the accumulator (A) by 10. The initial value of A is multiplied by 2 three times using the RLC instruction, and then the original value of A (stored in register B) is added to the result, resulting in a final multiplication by 10. Therefore, the correct answer is option 'B', which states that the content of A is multiplied by 10.
