What is arithmetic instructions in assembly language?
What is arithmetic instructions in assembly language?
The arithmetic instructions define the set of operations performed by the processor Arithmetic Logic Unit (ALU). The arithmetic instructions are further classified into binary, decimal, logical, shift/rotate, and bit/byte manipulation instructions.
What are 8086 instructions used for BCD arithmetic?
Arithmetic Instructions

| AAM | Adjust result of BCD Multiplication: This instruction is used after the multiplication of two unpacked BCD. |
Which are the operand for the arithmetic or logical program in 8086?
Logical instructions in 8086 microprocessor
| Opcode | Operand | Description |
|---|---|---|
| RCR | D,C | Used to rotate bits of byte/word towards the right, i.e. LSB to CF and CF to MSB. |
| RCL | D,C | Used to rotate bits of byte/word towards the left, i.e. MSB to CF and CF to LSB. |
Is 8086 a assembly language?
Simple 8086 Assembly Language Programs with Explanation. It is a most primitive machine level language is used to make efficient code that consumes less number of clock cycles and takes less memory as compared to the high-level programming language.
What are branch instructions in 8086?
List of 8086 Conditional Branch Instructions
| Instructions | Operation |
|---|---|
| JE/JZ | Jump if Equal/Jump if Zero |
| JG/JNLE | Jump if Greater/Jump if Not Less Than or Equal |
| JGE/JNL | Jump if Greater or Equal/Jump if Not Less Than |
| JL/JNGE | Jump if Less Than/Jump if Not Greater Than or Equal |
Which instruction is executed before an arithmetic operation?
Explanation: Since the operation, AAD is performed before division operation is performed, the carry flag, auxiliary flag and overflow flag are undefined. Explanation: In the TEST instruction, the logical AND operation is performed and the result is not stored but flags are affected.
How can I learn 8086 assembly?

- AX – the accumulator register (divided into AH / AL).
- BX – the base address register (divided into BH / BL).
- CX – the count register (divided into CH / CL).
- DX – the data register (divided into DH / DL).
- SI – source index register.
- DI – destination index register.
What are the basic rules of arithmetic?
The four basic arithmetic operations in Maths, for all real numbers, are:
- Addition (Finding the Sum; ‘+’)
- Subtraction (Finding the difference; ‘-‘)
- Multiplication (Finding the product; ‘×’ )
- Division (Finding the quotient; ‘÷’)
