In 8086 microprocessor, the destination operand need not be the accumulator. We will first discuss the working of each of these instructions and will then also discuss the syntax for each of them. … Use the shift and rotate instructions. Following is the list of instructions under this group − Instructions to perform logical operation… a) AND: Logical AND. Following is the table showing the list of logical instructions: OPCODE OPERAND DESTINATION EXAMPLE; AND: D, S: D = D AND S: AND AX, 0010: OR: D, S: D = D … Arithmetic and Logical Operations Chapter Nine There is a lot more to assembly language than knowing the operations of a handful of machine instructions. Instruction Set of 8086: An instruction defines the type of the operation. These instructions are used to perform operations where data bits are involved, i.e. Here D stands for destination, S stands for source and C stands for count. The 8086 provides many arithmetic operations: addition, subtraction, negation,multiplication and comparing two values.ADD :The add instruction adds the contents of the source operand to the destinationoperand.Eg.

A group of instructions are arranged in a pre defined manner to perform an operation. Therefore, this is all bout Assembly Level Programming 8086, 8086 Processor Architecture simple example programs for 8086 processors, Arithmetic and Logic Instructions.Furthermore, any queries regarding this article or electronics projects, you can contact us by commenting in …

Many instructions are useful for operations that have little to do with their mathematical or obvious functions. Logical instructions are the instructions which perform basic logical operations such as AND, OR, etc. In this article, we are going to study another type of instructions of the 8086 microprocessor which are used for shifting or rotating the contents of the register. Branch Instructions iv. Before transferring, the address of the next instruction after CALL is pushed onto the stack. Here D stands for destination, S stands for source and C stands for count. The Bit Manipulation Instructions in 8086 or Logical Instructions are NOT AND OR XOR TEST NOT Instruction : NOT destination.The NOT instruction inverts each

In 8086 microprocessor, the destination operand need not be the accumulator. Logical Instructions used in 8086 microprocessor 1. Este debate tiene 0 respuestas, 1 mensaje y ha sido actualizado por última vez el hace 1 año, 4 meses por fakrjru. Following is the table showing the list of logical instructions: Use AND, OR, and Exclusive -OR to accomplish binary bit manipulation. Instruction set of 8086 microprocessor can be divided into data copy/transfer instructions, arithmetic and logical instructions, branch/loop instructions, machine control instructions, flag manipulation instructions, string manipulation instructions.
