#TP ASSEMBLEUR EMU8086 CODE#

When the above code is compiled and executed, it produces the following result в€’ add '0' to to convert the sum from decimal to ASCII and subtracting ascii '0' to convert it into a decimal number moving the first number to eax register and second number to ebx Global _start must be declared for using gcc Msg2 db 'Please enter a second digit', 0xA,0xD The following example will ask two digits from the user, store the digits in the EAX and EBX register, respectively, add the values, store the result in a memory location ' res' and finally display the result. An ADD or SUB operation sets or clears the overflow and carry flags. However, like other instructions, memory-to-memory operations are not possible using ADD/SUB instructions. The ADD/SUB instruction can take place between в€’ The ADD and SUB instructions have the following syntax в€’ The ADD and SUB instructions are used for performing simple addition/subtraction of binary data in byte, word and doubleword size, i.e., for adding or subtracting 8-bit, 16-bit or 32-bit operands, respectively. The DEC instruction has the following syntax в€’ It works on a single operand that can be either in a register or in memory. The DEC instruction is used for decrementing an operand by one. The operand destination could be an 8-bit, 16-bit or 32-bit operand. The INC instruction has the following syntax в€’ The INC instruction is used for incrementing an operand by one.
