## What is 16bit multiplication?

16-bit multiplication is the multiplication of two 16-bit value from another. Such a multiplication results in a 32-bit value. Programming Tip: In fact, any multiplication results in an answer which is the sum of the bits in the two multiplicands.

**What is the register pair generally used while doing 16-bit multiplication?**

MUL is used to multiply two 16-bit numbers. HLT is used to stop the program. AX is an accumulator which is used to store the result. BX, DX are general purpose registers where BX is used for multiplication and DX is used for result.

**What is signed multiplication?**

Multiplying signed numbers: To multiply two real numbers that have the same sign, multiply their absolute values. The product is positive.

### What is the difference between the Imul and MUL instructions with an example?

Explanation: The MUL and IMUL are multiplication instructions. Here, MUL instructions used for multiplying unsigned numbers. On the other hand, IMUL multiplies signed numbers.

**When two unsigned 16-bit numbers are multiplied the number of bits in the product will be?**

First thing to remember is that the size of the product will be the sume of the sizes of the numbers being multiplied together. Since we are multiplying two 16-bit numbers, the size will be 32-bits.

**When we multiply two 16-bit numbers then result is stored in which pair of registers?**

Discussion. We can do multiplication in 8086 with MUL instruction. For 16-bit data the result may exceed the range, the higher order 16-bit values are stored at DX register.

## How does AAM work in 8086?

aam unpacks the AL result by dividing AL by 10, stores the quotient (most-significant digit) in AH, and stores the remainder (least-significant digit) in AL.

**What number system is base 16?**

Hexadecimal System

Hexadecimal System Hexadecimal is the name of the numbering system that is base 16. This system, therefore, has numerals 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15.

**Which instruction is used for signed multiplication?**

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….Description.

Instruction Form | Condition for Clearing OF and CF |
---|---|

r/m32 x EAX -> EDX:EAX | EDX:EAX= sign-extend of EAX to 32 bits |

### How do you multiply unsigned signed?

As far as hardware goes, unsigned multiplication and signed multiplication are exactly the same (ignoring flags). When you multiply 11111111 and 11111111 , the result is 00000001 , regardless of whether the inputs are considered to mean -1 or 255.

**What is 16 bit to 32 bit multiplication?**

16-bit Multiplication 16-bit multiplication is the multiplication of two 16-bit value from another. Such a multiplication results in a 32-bit value. Programming Tip: In fact, any multiplication results in an answer which is the sum of the bits in the two multiplicands.

**What is 1616-bit multiplication?**

16-bit multiplication is the multiplication of two 16-bit value from another. Such a multiplication results in a 32-bit value. Programming Tip: In fact, any multiplication results in an answer which is the sum of the bits in the two multiplicands. For example, multiplying an 8-bit value by a 16-bit value results in a 24-bit value (8 + 16).

## How do you multiply 16 bit numbers in 8086 assembly language?

Write 8086 Assembly language program to multiply two 16-bit number stored in memory location 3000H – 3001H and 3002H – 3003H. We can do multiplication in 8086 with MUL instruction. For 16-bit data the result may exceed the range, the higher order 16-bit values are stored at DX register. …

**How do you multiply bits in programming languages?**

Programming Tip: In fact, any multiplication results in an answer which is the sum of the bits in the two multiplicands. For example, multiplying an 8-bit value by a 16-bit value results in a 24-bit value (8 + 16). A 16-bit value multiplied by another 16-bit value results in a 32-bit value (16 + 16), etc.
