In 8086 there is MUL instruction. So the task is too simple. Here we are taking the numbers from memory and after that performing the multiplication operation. As 8-bit numbers are taken, after multiplication AX (16-bit. . languages such as C and C++. Learning to program in assemblylanguage is an excellent way to achieve this goal. Other PC assemblylanguage books still teach how to program the 8086 processor that the original PC used in 1981! The 8086 processor only supported real mode. In this mode, any program may address any memory or device in the computer. The basic four floating point arithmetic operations are addition, subtraction, multiplication, and division. Some processors don't include actual multiplication or division hardware, instead looking up the answer in a massive table of results embedded in the processor. Compare instructions are used to examine one or more floating point. The three-operand form of imul executes a signed multiply of a 16- or 32-bit immediate by a register or memory word or long and stores the product in a specified register word or long. imul clears the overflow and carry flags under the following conditions: Table 2-5 Clearing OR and CF Flags -- imul.

Inline assembly is the name given to assemblylanguage which is 'inlined' or 'embedded' into an existing program, usually a C or C++ program. GCC, which is the compiler I will be using as an example, allows this. ... Well, this is very much the same on the Intel processor. Multiplication, and division as well, are rather slow on the Intel.
This language helps in specifying the symbolic operand that means it does not need to specify the machine address of that operand. It can be represented in the form of a symbol. The data can be declared by using decimal notation. Assemblers The assemblers are used to translate the assembly language into machine language.
Successive multiplication is carried out. The product obtained in the registers. The output is stored in the registers. End. For example if we are trying to multiply two 16 bit numbers as below.We have divided 16 bit numbers into two 8 bit numbers
