8085 Program to Subtract two multi-Byte numbers
Now let us see a program of Intel 8085 Microprocessor. This program is mainly for subtracting multi Byte numbers.Problem Statement:Write 8085 Assembly language program to add two multi-Byte numbers.Discussion:We are using 3-Byte numbers. The numbers are stored into the memory at location 8001H and 8004H. One additional information is stored at location 8000H. In this place we are storing the Byte count. The result is stored at location 8050H.We are taking the address of first operand block address into DE register pair, and the second operand block address into HL pair. The BC register pair is storing the destination address ...

In this program, we will see how to find the square of an 8-bit number.Problem StatementWrite 8085 Assembly language program to find the square of a number The number is stored at location 8000H, store the result at 8050H.DiscussionIn 8085, we cannot perform the multiplication operation directly. We are performing the multiplication by using repetitive addition. To get square of a number, we have to multiply the number with itself.InputAddressData……80000C……Flow Diagram ProgramAddressHEX CodesLabelsMnemonicsCommentsF00021, 00, 80 LXI H, 8000HLoad the number from 8000HF003AF XRA AClear accumulatorF00446 MOV B, MLoad data from memory to BF00586LOOPADD MAdd memory byte with AF00605 DCR BDecrease B by 1F007C2, 05, F0 JNZ ...
Read MoreC++ Program to Perform Searching Using Self-Organizing Lists
Self-Organizing list basically updates the list of given range of items on the basis of last searched item. In this method, the sequential searching approach is used. This algorithm shifts the more important data to the beginning of the list. The time complexity of this search technique is O(n).AlgorithmBegin Function FibonacciSearch(). Calculate the mid value using ‘start+fib[index-2]’ expression. If the chosen item is equal to the value at mid index, print result and return to main. If it is lesser than the value at mid index, proceed with the left sub-array. If it is more ...

This example demonstrates How to display a button in random screen positionStep 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code to res/layout/activity_main.xml. In the above code, we have taken a button to move random position.Step 3 − Add the following code to src/MainActivity.javapackage com.example.myapplication; import android.os.Bundle; import android.support.v4.app.FragmentActivity; import android.util.DisplayMetrics; import android.widget.Button; import android.widget.LinearLayout; import java.util.Random; import java.util.Timer; import java.util.TimerTask; public class MainActivity extends FragmentActivity { @Override public void onCreate(Bundle savedInstanceState) ...
Read More8085 program to find minimum value of digit in the 8 bit number
In this program we will see how to find the minimum digit from a two-digit number.Problem StatementWrite 8085 Assembly language program to find the minimum digit from a two-digit number. The number is stored at location 8000H, store the result at 8050H.DiscussionHere we are performing this task by using masking operation. Each digit takes one nibbles. We are masking the upper nibble by ANDing with 0FH (0000 1111). Store the lower nibble into another register. After that, we are taking the upper nibble. To get it, we are shifting the number to the right four times to convert lower nibble ...
Read MoreC++ Program to Implement a Binary Search Algorithm for a Specific Search Sequence
In this Program we need to implement binary search to find the existence of a search sequence in an array. The time complexity of Binary search is O(log(n)).Required steps and pseudocodesBegin BinarySearch() function has ‘arr’ the array of data and ‘n’ the number of values, start and end index, iteration count and b[0] be the element to be searched in the argument list. Increment the iteration counter and compare the item value with the a[mid]. If item < a[mid] choose first half otherwise second half to proceed further. Return index value to main. In main(), ...

Read More8085 program to reverse 8 bit number
In this program we will see how to reverse the digits of an 8-bit number using 8085.Problem StatementWrite 8085 Assembly language program to reverse an 8-bit number stored at location 8000H. Also, store the result at 8050H.DiscussionHere the task is too simple. There are some rotating instructions in 8085. The RRC, RLC are used to rotate the Accumulator content to the right and left respectively without carry. We can use either RRC or RLC to perform this task.InputAddressData……80004C……Flow Diagram ProgramAddressHEX CodesLabelsMnemonicsCommentsF0003A, 00, 80 LDA 8000HTake the number from memoryF0030F RRCRotate right without carry four timesF0040F RRC F0050F RRC F0060F RRC F00732, 50, 80 STA 8050HStore the result at memoryF00A76 HLTTerminate the ...
