In this tutorial, we will learn the quicksort algorithm and its implementation in C. QuickSort is a sorting algorithm that works based on the divide-and-conquer strategy. It works as follows: Choose an element as pivot from the array. Position the pivot element in such a way that all elements less than the pivot appear before […]
Interrupt I/O is a data transfer method in which an external device informs the microprocessor that it is ready for communication and requests attention. The 8085 interrupt process is controlled by the Interrupt Enable flip-flop. The microprocessor is said to be interrupted when the flipflop is enabled and the signal INTR goes high. The instruction

A subroutine is a set of instructions that will be used repeatedly in different locations of the program. Instead of repeating the same instructions several times, they can be combined into a subroutine that is called from various locations. A subroutine in Assembly language can exist anywhere in the code. However, It is a common

In this tutorial, you will learn what is hashing, what a hash table is and what is a hash function. Hashing is a technique of mapping a large set of data into tabular indices. The importance of Hashing We know that the time complexity of search algorithms depends upon the number of elements in the
The stack in an 8085 can be described as a reserved area of the memory in the R/W memory where we can store temporary information. It is a shared resource as it can be shared by the microprocessor and the programmer. Programmers use the stack to store data and the microprocessors use the stack to
In this tutorial, you will learn about how the binary search algorithm works and its implementation using C. Searching is the process of finding whether or not a specific value exists in an array. The binary search algorithm can be used to search for an element in a sorted array. Working of Binary Search The
Looping in 8085 Looping is a programming technique that instructs the Microprocessor to repeat tasks. It is accomplished by changing the sequence of execution using jump instructions. Loops can be classified into two groups: Continous Loops. Conditional Loops. Continous Loops A continuous loops repeats a task continuously. It is setup by using unconditional jump instruction. A

In this tutorial, you will learn how the linear search algorithm works and its implementation using C. Searching is the process of finding whether or not a specific value exists in an array. The linear search or sequential search works by checking every element of the array one by one until a match is found. Working of Linear Search Consider the following array. we have to search for
8085 program to store a 8 bit data in memory MVI A, 24H – store 24H in the accumulator. STA 1423H – copy the contents of accumulator to memory loaction 1423H. HLT – stop the execution. 8085 program to add two 8 bit data numbers LXI H, 1500H – store the address of first number

The timing diagram is a graphical representation of the process in steps with respect to time. It represents the step by step working of each instruction and its execution. The execution time of instructions is represented in T-states. Machine Cycle– The time required to access the memory or input/output device is called the machine cycle.
