How can I add 16-bit number in 8086?

How can I add 16-bit number in 8086?

Algorithm –

1. Load 0000H into CX register (for carry)
2. Load the data into AX(accumulator) from memory 3000.
3. Load the data into BX register from memory 3002.
4. Add BX with Accumulator AX.
5. Jump if no carry.
6. Increment CX by 1.
7. Move data from AX(accumulator) to memory 3004.
8. Move data from CX register to memory 3006.

When you do division operation on two 16 bits numbers in 8086 microprocessor which of the following registers are used to store the quotient and remainder?

If the numerator is a 16-bit word and denominator is a byte, then AL and AH registers will store the quotient and remainder.

How many 16-bit segment registers does 8086 have *?

The 8086 has eight more or less general 16-bit registers (including the stack pointer but excluding the instruction pointer, flag register and segment registers). Four of them, AX, BX, CX, DX, can also be accessed as twice as many 8-bit registers (see figure) while the other four, SI, DI, BP, SP, are 16-bit only.

Do programs multiply 2 16-bit numbers?

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 find the 2s complement of a 16 bit number?

There is no direct way to find 2’s complement of the 16-bit number. Therefore, this can be accomplished by finding the 1’s complement of two 8-bit numbers and then incrementing it to get 2’s complement.

How do you calculate hexadecimal numbers?

Steps:

1. Divide the decimal number by 16. Treat the division as an integer division.
2. Write down the remainder (in hexadecimal).
3. Divide the result again by 16. Treat the division as an integer division.
4. Repeat step 2 and 3 until result is 0.
5. The hex value is the digit sequence of the remainders from the last to first.

How do you divide hexadecimal numbers?

Converting Decimal to Hex

1. Divide N by 16.
2. Divide the quotient from the last step by 16 again.
3. Divide the quotient from step 2 by 16 again.
4. Keep dividing your quotient from the last step by 16, and storing the remainder until the result of a division is 0.

What are hexadecimal numbers?

Hexadecimal describes a base-16 number system. That is, it describes a numbering system containing 16 sequential numbers as base units (including 0) before adding a new position for the next number. Two hexadecimal digits can represent eight binary digits, or a byte.

What is the value of 10102 in decimal?

What is 10102 decimal in binary? 10102 from decimal to binary is 10011101110110.

What is 9f16 in binary?

Answer. Warning. 9f1616 = 10011111000101102.

How many possible values can be created with only 2 bits?

A 2-bit system uses combinations of numbers up to two place values (11). There are four options: 00, 01, 10 and 11. A 1-bit image can have 2 colours, a 4-bit image can have 16, an 8-bit image can have 256, and a 16-bit image can have 65,536.
