Arithmetic Instruction In 8085, ADD, ADC, ADI, ACI

There are some of the important instructions in 8085 microprocessor.

1. ADD: - The content of operand are added to the content of the accumulator and the result is stored in Accumulator.

Eg- ADD B  (it adds the content of accumulator to the content of the register B)

     

      ADD M (if content is stored in memory location the it is added with the content stored in accumulator)

2. ADC: -

addition with carry

Eg:- ADC B  ,   ADC M

3. ADI: - Add immediate means add an immediate value withe the content of accumulator and it is stored in accumulator.

Eg: - ADI 30H

4. ACI: - Add immediate to accumulator with carry.

Eg: - ACI 40H
