In this program we will see how to transfer a block from one location to another location.Problem StatementWrite 8086 Assembly language program to transfer a block from one memory section to another memory section. The numbers are stored at memory offset 501 onwards. The block size is stored at memory offset 500.DiscussionHere we are initially setting up the source index register with the source of data blocks, then set the destination index register to store into another block. Then set the Data segment register and Extra Segment register to 0000H. By using MOVSB instruction, the entire block is transferred from ... Read More

In this program we will see how to transfer a 4-byte block from one location to another location.Problem StatementWrite 8086 Assembly language program to transfer a four-byte block from one memory section to another memory section. The numbers are stored at memory offset 500 – 503.DiscussionHere we are initially setting up the source index register with the source of data blocks, then set the destination index register to store into another block. Then set the Data segment register and Extra Segment register to 0000H. By using MOVSB instruction, the entire block is transferred from one location to another. As the ... Read More

In this program we will see how to sort array elements in ascending order by using selection sort.Problem StatementWrite 8086 Assembly language program to sort the elements in a given array using selection sort technique. The array is started from memory offset 501. The size of the series is stored at memory offset 500.DiscussionIn the selection sort technique, in each phase we are taking the smallest number from the array, swap the smallest element with the first element inside the array. Then move to second position, and check for second highest number form the second position to the end of ... Read More

In this program we will see how to sort array elements in ascending order.Problem StatementWrite 8086 Assembly language program to sort the elements in a given array, which is starts from memory offset 501. The size of the series is stored at memory offset 500.DiscussionHere we are sorting the number in bubble sorting technique. In this sorting technique there will be n passes for n different numbers. In ith pass the ith largest element will be placed at the end. This is comparison based sort. We taking two consecutive numbers, compare them, and then swap them if the numbers are ... Read More

In this program we will see how to find the minimum number in a given array.Problem StatementWrite 8086 Assembly language program to find the minimum number in a given array, which is starts from memory offset 501. The size of the series is stored at memory offset 500. Store the minimum number at memory offset 600.DiscussionAt first we are taking the size of the array from memory offset 500. Then using that size, we are initializing the counter to read and check all the numbers. We are taking the first number into AL, then check each number and compare it ... Read More

In this program we will see how to find the largest number in a given array.Problem StatementWrite 8086 Assembly language program to find the largest number in a given array, which is starts from memory offset 501. The size of the series is stored at memory offset 500. Store the largest number at memory offset 600.DiscussionAt first we are taking the size of the array from memory offset 500. Then using that size, we are initializing the counter to read and check all the numbers. We are taking the first number into AL, then check each number and compare it ... Read More

In this program we will see how to find the equivalent BCD number from an ASCII value.Problem StatementWrite 8086 Assembly language program to find the equivalent BCD number from an ASCII value. The number is stored at memory location 2050 and store the result at memory location 3050.DiscussionThis program can change ASCII value of a number to its BCD (Decimal) form. The ASCII values of the numbers are like below:ASCII (in Hex)30313233343536373839BCD00010203040506070809 From this table we can easily find that the last nibble of the ASCII value is actually the BCD equivalent. So to take the last nibble we have masked ... Read More

In this program we will see how to find the equivalent hexadecimal number from a BCD number.Problem StatementWrite 8086 Assembly language program to find the equivalent hexadecimal number from a BCD number. The number is stored at memory offset 500 and store the result at memory offset 600.DiscussionTo convert BCD to hexadecimal at first we have to cut the BCD digits. The most significant digit will be multiplied with 0AH (10D), and then least significant digit will be added with the result of multiplication. Thus the BCD will be converted to its equivalent hexadecimal form.InputAddressData……50059…… Flow Diagram ProgramOutputAddressData……6003B……

In this program we will see how to find the gray code from a binary number.Problem StatementWrite 8086 Assembly language program to find the equivalent gray code from a binary number. The number is stored at location 2500 and store the result at 2600.DiscussionTo convert binary to gray code, we have to shift the number one bit to the right, then XOR with the previous number. Thus the gray code will be generated. For a number 2C (0010 1100) the gray code will be 3A (0011 1010)InputAddressData……25002C…… Flow Diagram Program OutputAddressData……26003A……

In this program we will see how to find the square root of a perfect squared.Problem StatementWrite 8086 Assembly language program to find the square root of a perfect squared number. The number is stored at memory address 3000. Finally store the result at memory address 3002.DiscussionFor the perfect square number starting from 0 we are performing square of it, then check whether it is same as the given number or not. If they are same then the current value will be the square root.For a number 51H (81D), we will check 02, 12, 22, ….. , 92. After 92 ... Read More
