8085 Assembly language programming code for beginners

Addition of two 8 bit numbers.

Code:

   MVI B, 06
   //Load Register B with the Hex value 06
   MOV A, B
   //Move the value in B to the Accumulator or register A
   MVI C, 07
   //Load the Register C with the second number 07
   ADD C
   //Add the content of the Accumulator to the Register C
   STA 8200
   //Store the output at a memory location e.g. 8200
   HLT
   //Stop the program execution
   

Addition of two 8 bit numbers stored in memory

Code:

   LDA 8500
   //Load the accumulator with the address of memory viz 8500
   MOV B, A
   Move the accumulator value to the register B
   LDA 8501
   //Load the accumulator with the address of memory viz 8501
   ADD B
   //Add the content of the Accumulator to the Register B
   STA 8502
   //Store the output at a memory location e.g. 8502
   HLT
   //Stop the program execution
   

Addition of two 8 bit numbers stored in memory and storing the carry

Code:

   LDA 8500
   //Load the accumulator with the address of memory viz 8500
   MOV B, A
   Move the accumulator value to the register B
   LDA 8501
   //Load the accumulator with the address of memory viz 8501
   ADD B
   //Add the content of the Accumulator to the Register B
   STA 8502
   //Store the output at a memory location e.g. 8502
   MVI A, 00
   //clear the accumulator with 00
   ADC A
   //Add with carry the content of the accumulator
   STA 8503
   //Store the output at a memory location e.g. 8503
   HLT
   //Stop the program execution
   

Implementing the above program for the subtraction is very simple just replace ADD with SUB and ADC with SBB and all should be working fine.

Just create a new thread about the problem you are facing and definitely some members and experts will try to help you out.

santu1225 Welcome to G4EF.

 

Which program you are talking about.

 

I mean to say which square root program you are talking about.

 

I would suggest you couple of things.

1. Dont jump into some thread without any context as that will take longer for you to make someone understand what you are looking for.
2. We are not here to complete your assignments but its you who need to be doing that. Its just that we can assist you.

Also Please go through [thread=168]this[/thread].
