The ADD instruction adds the value in the source operand to the value in the destination operand and stores the result in the destination operand.

C. Step-by-step walkthrough of Addition problems in Assembly language

Let's walk through an example to understand how addition is performed in Assembly language:

MOV AX, 5
ADD AX, 3

In this example, we first move the value 5 into the AX register using the MOV instruction. Then, we add the value 3 to the AX register using the ADD instruction. The result of the addition, 8, is stored in the AX register.

D. Real-world applications and examples of Addition in Mechatronics

Addition is used in various real-world applications in Mechatronics. For example, in robotics, addition is used to calculate the position of a robot arm based on the joint angles. In control systems, addition is used to combine different signals or error terms.

E. Advantages and disadvantages of using Addition in Assembly language

Some advantages of using addition in Assembly language include its simplicity and efficiency. Addition operations can be performed quickly and accurately using the dedicated instructions available in Assembly language.

However, one disadvantage of using addition in Assembly language is the limited range of numbers that can be represented. Assembly language typically uses fixed-size registers, which can only hold a certain number of bits. This limits the range of numbers that can be added without overflow or underflow errors.

III. Subtraction in Assembly language

A. Explanation of Subtraction operation

Subtraction is another basic mathematical operation that finds the difference between two numbers. In Assembly language, subtraction is performed using specific instructions that manipulate the binary representation of numbers.

B. Syntax and usage of Subtraction in Assembly language

To perform subtraction in Assembly language, we use the SUB instruction. The syntax for the SUB instruction is as follows:

SUB destination, source

The SUB instruction subtracts the value in the source operand from the value in the destination operand and stores the result in the destination operand.

C. Step-by-step walkthrough of Subtraction problems in Assembly language

Let's walk through an example to understand how subtraction is performed in Assembly language:

MOV AX, 8
SUB AX, 3

In this example, we first move the value 8 into the AX register using the MOV instruction. Then, we subtract the value 3 from the AX register using the SUB instruction. The result of the subtraction, 5, is stored in the AX register.

D. Real-world applications and examples of Subtraction in Mechatronics

Subtraction is used in various real-world applications in Mechatronics. For example, in control systems, subtraction is used to calculate the error between the desired and actual values. In signal processing, subtraction is used to remove noise or interference from a signal.

E. Advantages and disadvantages of using Subtraction in Assembly language

Some advantages of using subtraction in Assembly language include its simplicity and efficiency. Subtraction operations can be performed quickly and accurately using the dedicated instructions available in Assembly language.

However, similar to addition, one disadvantage of using subtraction in Assembly language is the limited range of numbers that can be represented. Assembly language typically uses fixed-size registers, which can only hold a certain number of bits. This limits the range of numbers that can be subtracted without overflow or underflow errors.

IV. Multiplication in Assembly language

A. Explanation of Multiplication operation

Multiplication is a mathematical operation that finds the product of two or more numbers. In Assembly language, multiplication is performed using specific instructions that manipulate the binary representation of numbers.

B. Syntax and usage of Multiplication in Assembly language

To perform multiplication in Assembly language, we use the MUL instruction. The syntax for the MUL instruction is as follows:

MUL source

The MUL instruction multiplies the value in the AX register by the value in the source operand and stores the result in the DX:AX register pair.

C. Step-by-step walkthrough of Multiplication problems in Assembly language

Let's walk through an example to understand how multiplication is performed in Assembly language:

MOV AX, 5
MUL AX, 3

In this example, we first move the value 5 into the AX register using the MOV instruction. Then, we multiply the value in the AX register by 3 using the MUL instruction. The result of the multiplication, 15, is stored in the DX:AX register pair.

D. Real-world applications and examples of Multiplication in Mechatronics

Multiplication is used in various real-world applications in Mechatronics. For example, in robotics, multiplication is used to calculate the torque required to move a robot arm. In signal processing, multiplication is used to modulate or demodulate a signal.

E. Advantages and disadvantages of using Multiplication in Assembly language
