How do you divide in Assembly in 8086?
Algorithm –
- Assign value 500 in SI and 600 in DI.
- Move the contents of [SI] in BL and increment SI by 1.
- Move the contents of [SI] and [SI + 1] in AX.
- Use DIV instruction to divide AX by BL.
- Move the contents of AX in [DI].
- Halt the program.
What are the 3 sections of assembly program?
Assembly – Basic Syntax An assembly program can be divided into three sections − •The data section, •The bss section, and •The text section.
What is the operation performed by Div BX?
2 Answers. The DIV BX instruction divides the 32-bit value in DX:AX by BX.
How do you divide in an arm assembly?
For example, two 64-bit registers can be multiplied to produce a 64-bit result with the MUL instruction. There is also the ability to add or subtract an accumulator value in a third source register, using the MADD or MSUB instructions….Multiply and divide instructions.

| SDIV | Signed divide |
| UDIV | Unsigned divide |
What is the size of divided in case of 16 bit division?
After division, the 16-bit quotient goes to the AX register and the 16-bit remainder goes to the DX register. The dividend is assumed to be 64 bits long and in the EDX:EAX registers.
What is the size of divided in case of 16bit division?
For example, it is possible to divide 16 or 32 bit dividend by 16 bit divisor to 16 bit quotient in just one routine. Note that in some cases it is known that the result of 32 bit by 16 bit division is 16 bit maximum.
How do you do arm division?
A 64 × 64 to 128-bit multiply requires a sequence of two instructions to generate a pair of 64-bit result registers: ± (64 × 64) gives the lower 64 bits of the result [63:0]….Multiply and divide instructions.

What are different sections in assembly?
Sections that an assembly language programmer can manipulate by issuing section control directives in the source file are user sections. The predefined user sections are those predefined sections that are also user sections. Table 3-4 lists the names of the predefined user sections and briefly describes each.
How many sections are there in each assembly programs?
We have already discussed the three sections of an assembly program. These sections represent various memory segments as well.
What is Imul Assembly?
Description. The single-operand form of imul executes a signed multiply of a byte, word, or long by the contents of the AL, AX, or EAX register and stores the product in the AX, DX:AX or EDX:EAX register respectively.
What is a DIV instruction?
Purpose. Divides the contents of a general-purpose register concatenated with the MQ Register by the contents of a general-purpose register and stores the result in a general-purpose register.
What is Div instruction in 8086?
8086 DIV Instruction ( Unsigned Operands) The DIV instruction performs the division of two unsigned operands. The denominator resides in a source operand and it should not be immediate. However, it can be register or a memory location. There are four division cases depending on the number of bits. The division can be: Byte with byte; Word with word
What are the instructions supported by 8086 microprocessor?
In this series on 8086 microprocessor tutorials, we previously discussed; 8086 Microprocessor Addressing Modes, 8086 Data Transfer Instructions, 8086 Integer Arithmetic Instructions, 8086 Integer Multiplication Instructions. The following instructions are supported by 8086 microprocessor that are used to perform the division operation:
What is IDIV instruction in 8086?
8086 IDIV Instruction (Signed Operands) IDIV is an arithmetic instruction that performs a division operation between two signed numbers. The source operand in the instruction is a signed divisor. It can be specified using any addressing mode except immediate mode of addressing.
Which register holds the denominator in the division instruction?
After division, the instruction stores quotient in AL and the remainder in AH register. The DIV instruction divides BH by AL. F2 divided by 04 gives quotient of 3C and give 02 as a remainder. AL stores the quotient and remainder is stored in AH register. In this case, the AX register holds the denominator.
