write an 8086 assembly program that 1) adds two operand. 2) that adds operands until the new value to be added is 0. 3) Write a program that increments by 2 the content of a register 10 times.
8086 assembly program that
1) adds two operand.
main:
push rbp
mov rbp, rsp
mov DWORD PTR [rbp-4], 0
mov DWORD PTR [rbp-8], 6
mov DWORD PTR [rbp-12], 5
mov edx, DWORD PTR [rbp-8]
mov eax, DWORD PTR [rbp-12]
add eax, edx
mov DWORD PTR [rbp-4], eax
mov eax, 0
pop rbp
ret
2) that adds operands until the new value to be added is 0.
.LC0:
.string "%d"
main:
push rbp
mov rbp, rsp
sub rsp, 16
mov DWORD PTR [rbp-4], 0
mov DWORD PTR [rbp-8], 0
.L3:
lea rax, [rbp-8]
mov rsi, rax
mov edi, OFFSET FLAT:.LC0
mov eax, 0
call scanf
mov eax, DWORD PTR [rbp-8]
add DWORD PTR [rbp-4], eax
mov eax, DWORD PTR [rbp-8]
test eax, eax
je .L2
jmp .L3
.L2:
mov eax, 0
leave
ret
3) Write a program that increments by 2 the content of a register 10 times.
.LC0:
.string "Increment by 2 "
main:
push rbp
mov rbp, rsp
sub rsp, 16
mov DWORD PTR [rbp-8], 20
.L3:
cmp DWORD PTR [rbp-8], 0
je .L2
add DWORD PTR [rbp-4], 2
jmp .L3
.L2:
mov edi, OFFSET FLAT:.LC0
mov eax, 0
call printf
mov eax, 0

Please write in assembly language 8086 windows32 Question 3: Write an assembly program that has a macro maximum that finds the larger of two numbers inputted by the user
Write an 8086 assembly program to compute the following: y = 3x + 9x - 10 where x and y are 32-bit integer variables. x is in the range of (1 = < x < = 8). y is a list (use DUP when identifying and initializing y list). y only contains the result of x = 1, 3, 5, and 7. Use if-statement and while loop. The values of the y list after running the program should be: 2,...
Code in assembly language please "Write an assembly 32 bit program that adds two numbers (other than 5 and 6) and stores the value to a variable called 'sum'. Also, use a block COMMENT to depict the name and description of the program, author of the program, and date."
(50 pts) Write a program that asks user an arithmetic operator('+','−','∗' or '/') and two operands and perform the corresponding calculation on the operands. Specific requirements: (1) Your main function accepts inputs and display calculation result. (2) Write four functions to perform the four calculations. Call these functions in your main function. (3) Repeatedly asks for inputs, calculate and display result until user input nonnumeric value for operands. Hint: you can put getchar() right after scanf() to get rid of...
Q 2. Assuming a 32-bit operating environment, identify the mode of each operand in the following instructions. (Note: There are two operands in each instruction; identify both modes.) For a memory operand, specify whether it is direct memory mode or register indirect memory mode. Assume that the instructions are in a program also containing the code. .DATA value DWORD ? char BYTE *1. mov value, 100 2. movecx, value 3. mov ah, Oah *4. moveax, (esi] 5. mov [ebx], ecx...

The input will be in the following format: Opl op op2- There is no space between operands and operator. I Note 5/2-quotient 2, remainder 1 2$3-8 The output should be of the form 2 3-6 Read date from a file Upload the source code, executable and output TEST DATA: AAAA+BBF- BFD+2DE 100...
Write the hexadecimal notation for a MIPS machine language program that adds 42 to the value in register 2 placing the result in register 3 and then returns. Example of running the program: Enter value for register 1: 2 Enter value for register 2: 3 Running MIPS program. MIPS program completed normally. $01 = 0x00000002 $02 = 0x00000003 $03 = 0x0000002D ...

Write a TM (Turing Machine) program that adds two base two numbers. Input is two nonnegative integers in base 2 with a plus sign between them. Output is their sum in base 2, with nothing else left on the tape. So first decrement, then increment. Use an online Turing Machine Simulator to see how it works. Use the following language for the program: current state, read symbol, next state, write symbol, direction [directions are (< left, > right, s stay)]...
