What are logical instructions in assembly language?
Logical instructions in assembly language perform bitwise operations and logical comparisons on binary data.
Bitwise AND (and)
Performs a bitwise AND operation between corresponding bits of two operands.
Bitwise OR (or)
Performs a bitwise OR operation between corresponding bits of two operands.
Bitwise XOR (xor)
Performs a bitwise XOR (exclusive OR) operation between corresponding bits of two operands.
Bitwise NOT (not)
Inverts the bits of the operand, changing 0s to 1s and vice versa.
Performs a bitwise AND operation for setting flags without changing the operand.
Here are some additional examples of how logical instructions can be used in assembly language:
Logical instructions perform bitwise operations like AND, OR, XOR, and NOT, allowing manipulation and comparison of individual bits in binary data. These operations are fundamental for tasks such as masking, setting, clearing specific bits, and logical comparisons in low-level programming.
