16 BIT SUBTRACTION
USING ARITHMETIC OPERATION OF 8086 MICROPROCESSOR
AIM:
To write an assembly language program to perform subtraction of two 16 bit
numbers using 8086.
APPARATUS REQUIRED:
S.NO ITEM SPECIFICATION QUANTITY
1. MICROPROCESSOR KIR 8086 KIT 1
2. POWER SUPPLY + 5 V DC 1
3. KEY BOARD - 1
ALGORITHM:
16-bit SUBTRACTION:
Initialize the MSBs of difference to 0
Get the first number
Subtract the second number from the first number.
If there is any borrow, increment MSBs of difference by 1.
Store LSBs of difference.
Store MSBs of difference.

16 BIT MULTIPLICATION USING ARITHMETIC OPERATION OF 8086
MICROPROCESSOR
AIM:
To write an assembly language program to perform Multiplication of two 16
bit numbers using 8086.
APPARATUS REQUIRED:
S.NO ITEM SPECIFICATION QUANTITY
1. MICROPROCESSOR KIR 8086 KIT 1
2. POWER SUPPLY + 5 V DC 1
3. KEY BOARD - 1
ALGORITHM:
16-bit MULTIPLICATION
Multiplication of 16-bit numbers:
Get the multiplier.
Get the multiplicand
Initialize the product to 0.
Product = product + multiplicand
Decrement the multiplier by 1.
If multiplicand is not equal to 0, repeat from step (d) otherwise store the
product.

16 BIT DIVISION USING ARITHMETIC OPERATION OF 8086 MICROPROCESSOR
AIM:
To write an assembly language program to perform division of two 16 bit
numbers using 8086.
APPARATUS REQUIRED:
S.NO ITEM SPECIFICATION QUANTITY
1. MICROPROCESSOR KIT 8086 KIT 1
2. POWER SUPPLY + 5 V DC 1
3. KEY BOARD - 1
ALGORITHM:
16-bit division
Division of 16-bit numbers:
Get the dividend and divisor.
Initialize the quotient to 0.
Dividend = dividend–divisor
If the divisor is greater, store the quotient
Go to step 3
If dividend is greater, quotient = quotient+ repeat from step 4.

MOVE A DATA BLOCK WITHOUT OVERLAP
AIM:
To move a data block without overlap
APPARATUS REQUIRED:
S.NO ITEM SPECIFICATION QUANTITY
1. MICROPROCESSOR KIR 8086 KIT 1
2. POWER SUPPLY + 5 V DC 1
3. KEY BOARD - 1
ALGORITHM:
Initialize the memory location to the data pointer.
Increment B register.
Increment accumulator by 1 and adjust it to decimal every time.
Compare the given decimal number with accumulator value.
When both match, the equivalent hexadecimal value is in B register.
Store the resultant in memory location.
