## How do you multiply two numbers in assembly?

## How do you multiply two numbers in assembly?

Step I : Initialize the data segment. Step II : Get the first number in AL register. Step III : Get the second number in BL register. Step IV : Multiply the two numbers.

## How do you multiply in assembly language?

The MUL/IMUL Instruction There are two instructions for multiplying binary data. The MUL (Multiply) instruction handles unsigned data and the IMUL (Integer Multiply) handles signed data. Both instructions affect the Carry and Overflow flag.

**How do you write a program to multiply two numbers?**

Program to Multiply Two Numbers printf(“Enter two numbers: “); scanf(“%lf %lf”, &a, &b); Then, the product of a and b is evaluated and the result is stored in product . product = a * b; Finally, product is displayed on the screen using printf() .

### How do you do multiplication in 8086?

Algorithm –

- First load the data into AX(accumulator) from memory 3000.
- Load the data into BX register from memory 3002.
- Multiply BX with Accumulator AX.
- Move data from AX(accumulator) to memory.
- Move data from DX to AX.
- Move data from AX(accumulator) to memory.
- Stop.

### What is AAM in assembly language?

ASCII Adjust after Multiplication(AAM): Corrects the result of multiplication of two BCD values.

**Which instruction performs multiply by by 2 operation?**

The arithmetic shift operations are often used in power of two arithmetic operations (such a multiply by two), as the instructions are much faster than the equivalent multiply or divide operation.

## What is MUL in ARM?

The MUL instruction multiplies the values from and , and places the least significant 32 bits of the result in .

## Which algorithm is used for multiplication operations in ARM processor?

The implementation is done using the Karatsuba algorithm. The 416-bit inputs are split into a lower 224-bit and an upper 192-bit. The 224-bit integer is further split into a lower 128 and higher 96-bit.

**What does MUL do in 8086?**

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.

### How do you do multiplication in 8085?

The 8085 has no multiplication operation. To get the result of multiplication, we should use the repetitive addition method. After multiplying two 8-bit numbers it may generate 1-byte or 2-byte numbers, so we are using two registers to hold the result. We are saving the data at location 8000H and 8001H.

### How does MUL instruction work?

The mul instruction multiplies the contents of general-purpose register (GPR) RA and GPR RB, and stores bits 0-31 of the result in the target GPR RT and bits 32-63 of the result in the MQ Register. The mul instruction has four syntax forms.

**How to multiply two 8 bit numbers in assembly language?**

Write a program to Multiply Two 8 Bit Numbers in assembly language . Program should load first number and second number in registers AL and BL registers . Then it should implement some logic for multiplication of two numbers . Consider that a byte of data is present in the AL register and second byte of data is present in the BL register.

## How to multiply two numbers in a program?

Program should load first number and second number in registers AL and BL registers . Then it should implement some logic for multiplication of two numbers . Consider that a byte of data is present in the AL register and second byte of data is present in the BL register.

## How to multiply two numbers with Al Register?

Now, we have understood part of it to multiply two number With AL register (BY DEFAULT) we can write MUL NUM1 and MUL BL provided the value to be multiplied is passed to BL register in prior. Now, the Resultant Value is saved in Accumalator AX for DB and (DX AX) for DW]

**How to multiply the contents of two registers using Mul?**

We have to multiply the byte in AL with the byte in BL. Using MUL instruction, multiply the contents of two registers. The multiplication of two 8 bit numbers may result into a 16 bit number. So result is stored in AX register. The MSB is stored in AH and LSB in AL.
