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 16-bit data 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.

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.

Which instruction is used to add 16-bit no?

Following this, we use the instruction adc – add with carry – to add the upper bytes of our 16-bit numbers. adc is used just like add, taking two registers as operands, computing their sum, and storing the result in the first register.

What is the correct 8085 assembly language instruction that stores the contents of H and L registers into the memory locations 2500h and 2501h respectively?

The 8085 assembly language instruction that stores the contents of H and L registers into the memory locations 2050H and 2051H, respectively, is: Q9. Directions: It consists of two statements, one labelled as the ‘Statement (I)’ and the other as ‘Statement (II).

How a program is executed by microprocessor 8085?

The instructions which are to be executed by microprocessor are first stored in the memory of the processor and then executed. But the processor does not execute the instructions directly. It reads the instruction byte by byte and then executes it.

What are steps of execution of microprocessor 8085?

Execution cycle – consists memory read (MR), memory write (MW), input output read (IOR) and input output write (IOW)
