8086 Assembly Language Programs for Arithmetic Operations

AIM

To write and execute Assembly Language Programs to perform arithmetic operations for the 8086 microprocessor.

APPARATUS REQUIRED

• Personal Computer with MASM Software

1. ADDITION

Algorithm

1. Initialize memory location in HL register.
2. Store 1st data.
3. Increment HL to enter 2nd data.
4. Move 2nd number to accumulator.
5. Decrement HL.
6. Add value in memory with accumulator.
7. Store result.
8. Stop.
