Program To Add Numbers Using Register Addressing In Assembly Language Problem: write an assembly language program to add two 16 bit numbers by using: 8 bit operation16 bit operation example: 1. addition of 16 bit numbers using 8 bit operation: it is a lengthy method and requires more memory as compared to the 16 bit operation. algorithm: load the lower part of the first number in the b register.load the lower part of. The 8086 memory addressing modes provide flexible access to memory, allowing you to easily access variables, arrays, records, pointers, and other complex data types. the key to good assembly language programming is the proper use of memory addressing modes. an assembly language program instruction consists of two parts.
Program To Add Numbers Using Register Addressing In Assembly Language Section .text global start. start: ; load the first number (num1) into eax mov eax, [num1] ; add the second number (num2) to eax. add eax, [num2] ; store the result in the result variable (byte) mov [result], al. ; display the result on the screen. ; for linux, you can use the syscall to write to the console. Assembly addressing modes. most assembly language instructions require operands to be processed. an operand address provides the location, where the data to be processed is stored. some instructions do not require an operand, whereas some other instructions may require one, two, or three operands. when an instruction requires two operands. Problem: write an assembly language program to add two 16 bit numbers by using: 8 bit operation16 bit operation example: 1. addition of 16 bit numbers using 8 bit operation: it is a lengthy method and requires more memory as compared to the 16 bit operation. algorithm: load the lower part of the first number in the b register.load the lower part of. The instructions mov bx, 255 copies decimal value 255 to register bx. you cannot use the immediate addressing mode to load immediate value into segment registers. to move any value into segment registers, first load that value into a general purpose register then add this value into segment register. example assembly code.

Instruction set of 8086. the 8086 instructions are categorized into the following main types. data copy transfer instructions: these type of instructions are used to transfer data from source operand. to destination operand. all the store, load, move, exchange input and output instructions belong to this. category. Algorithm to add two 8 bit numbers. step 1 : initialize the data segment. step 2 : get the first number in al register. step 3 : get the second number in bl register. step 4 : add the two numbers. step 5 : display the result. step 6 : stop.
