How can add two numbers in assembly language 8085?

Algorithm –

  1. Load the first number from memory location 2050 to accumulator.
  2. Move the content of accumulator to register H.
  3. Load the second number from memory location 2051 to accumaltor.
  4. Then add the content of register H and accumulator using “ADD” instruction and storing result at 3050.

How can I add two 16-bit numbers in 8085?

Algorithm –

  1. Load both the lower and the higher bits of first number at once.
  2. Copy the first number to another register pair.
  3. Load both the lower and the higher bits of second number at once.
  4. Add both the register pairs and store the result in a memory location.

Which instruction is used to add two bytes with adding carry?

When adding two 16-bit data operands, we need to be concerned with the propagation of a carry from the lower byte to the higher byte. The instruction ADDC (add with carry) is used on such occasions.

How can I add 10 numbers in 8085?

Algorithm –

  1. Load the base address of the array in HL register pair.
  2. Use the size of the array as a counter.
  3. Initialise accumulator to 00.
  4. Add content of accumulator with the content stored at memory location given in HL pair.
  5. Decrease counter on each addition.

How can add two numbers in assembly language 8086?

Algorithm –

  1. Load 0000H into CX register (for carry)
  2. Load the data into AX(accumulator) from memory 3000.
  3. Load the data into BX register from memory 3002.
  4. Add BX with Accumulator AX.
  5. Jump if no carry.
  6. Increment CX by 1.
  7. Move data from AX(accumulator) to memory 3004.
  8. Move data from CX register to memory 3006.

How do you add two 16-bit numbers in assembly language?

Algorithm to Add Two 16 Bit Numbers

  1. Step I : Initialize the data segment.
  2. Step II : Get the first number in AX register.
  3. Step III : Get the second number in BX register.
  4. Step IV : Add the two numbers.
  5. Step V : Display the result.

How can I add two 32 bit numbers in 8085?

Step I : Initialize the data segment.

  1. Step II : Load the LSB of first number into AX register.
  2. Step III : Load the MSB of first number into BX register.
  3. Step IV : Load the LSB of the second number into CX register.
  4. Step V : Load the MSB of the second number into DX register.
  5. Step VI : Add the LSBs of two number.

What is ADD instruction?

ADD Instruction. The ADD instruction performs an addition on both the first source register’s contents and the second source. register’s contents, and stores the result in the destination register. It’s syntax is: ADD $destination register’s address, $first source register’s address, $second source register’s address.

What is LXI instruction in microprocessor?

We can use this instruction to load data from memory location using the memory address, which is stored in the register pair rp. For an example, if the instruction is LXI H, FE50. It means that the FE50 is loaded into the HL register pair.

How do you add two 16 bit numbers in assembly language?

How to add two 8 bit numbers using 8085 microprocessor?

ADDITION OF TWO 8 BIT NUMBERS AIM: To perform addition of two 8 bit numbers using 8085. ALGORITHM: 1) Start the program by loading the first data into Accumulator. 2) Move the data to a register (B register). 3) Get the second data and load into Accumulator. 4) Add the two register contents. 5) Check for carry.

Do I need to learn assembler for 8085?

In the first place, you’d better learn how to write 8085 if you expect to use it. Assembler, especially for old 8-bit microprocessors, is not something you can just take canned software and patch in. In the second place, exactly what are you using for numbers? The 8085 has an 8-bit bus and can use registers as 16 bits.

How to add two 8-bit numbers in assembly language?

Write8085 Assembly language program to add two 8-bit numbers and store the result at locations 8050H and 8051H. To perform this task, we are using the ADD operation of 8085 Microprocessor. When the result of the addition is the 1-byte result, then the carry flag will not be enabled.

How to enable the carry flag in 8085 microprocessor?

To perform this task, we are using the ADD operation of 8085 Microprocessor. When the result of the addition is the 1-byte result, then the carry flag will not be enabled. When the result is exceeding the 1-byte range, then the carry flag will be 1
