We have assumed that the interrupt system gets enabled by using the EI instruction, and the signals which have higher priority are not in active state.In the penultimate clock cycle of the last machine cycle of every instruction, the 8085 senses all the internal interrupt signals.If the INTR internal signal which is at logic 1, the 8085 enters to a machine cycle which is called interrupt acknowledge (INA) machine cycle.The interrupts from the Input Output port gets acknowledged by the 8085 by the activation of INTA* pin in the T2 state of the machine cycle INA where INTA* is a ...

Before getting into example, we should know what sqlite data base in android is. SQLite is an open source SQL database that stores data to a text file on a device. Android comes in with built in SQLite database implementation. SQLite supports all the relational database features. In order to access this database, you don't need to establish any kind of connections for it like JDBC, ODBC etc.This example demonstrates How to drop table in Android sqlite.Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a ...

You can use $pull operator to remove the object from an array in MongoDB. To understand the concept, let us create a collection with the document. The query to create a collection with a document is as follows −> db.removeObjectFromArrayDemo.insertOne( ... { ... ... "StudentName": "John", ... "StudentAcademicProjectDetails": ... [{ ... "StudentProjectId": 101, ... "StudentProjectName": "Pig Dice Game" ... }, ... { ... "StudentProjectId": 110, ... "StudentProjectName": "Library Management System" ... ... Read More
What is phyllotaxis pattern?When we go back, in our botany classes and the plant world, phyllotaxis means the arrangement of flowers, leaves or seeds on a plant stem, similar to the one found in Fibonacci spiral. Based on Fibonacci sequence, the Fibonacci spiral is a set of numbers that follows a pattern similar on pascal’s triangle. The Fibonacci sequence numbers are something like - 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, etc. So the Fibonacci sequence number is the sum of its previous numbers.Fibonacci spiralsWe generally look for symmetry and patterns to understand the objects ...

In this article we will see how to add two numbers without using arithmetic operators like +, ++, -, or --.To solve this problem, we can solve them using binary adder logic. In that case we were designed half adder and full adder. These adders can add one bit binary numbers. By cascading multiple adders, we have can create circuit to add bigger numbers.In that adder, we have performed XOR operation among the numbers, then for the carry we were performing the ANDing logic. These features are implemented here to add two numbers.Example Code Live Demo#include using namespace std; int ... Read More
