Data Structures - Linked List, Stack, Queue, and Tree
An array is a simple data structure in which each element can be accessed directly. But what about storing an item whose size may vary? And what about removing an item if the relative positions of the remaining items must be preserved? In such situations other data structures may be needed. More ...
Computer Video Display
If you view a computer as an input-processing-output machine, you can use a keyboard or removable storage device as the input, a program as the processing, but what can you use to retrieve the output? One way to acquire the output, be it text or graphics, is with a video display. More ...
Binary Floating-Point Numbers
Floating-point numbers allow you to use the very large, and very small, numbers commonly found in scientific calculations. A binary floating-point number consists of three parts, the sign bit, the mantissa and the exponent. More ...
Difference between Stack, Heap, and Queue
Stack, heap, and queue are ways that elements are stored in memory. Stack elements are added to the top of the stack, and removed from the top of the stack. The mnemonic LIFO is used to describe a stack (Last-In-First-Out). With a queue, the first one in is the first one out. The mnemonic FIFO is used to describe a queue. A heap is an area of memory where elements can be stored and removed in any order. More ...
Integrated Circuit Design Flow
The process of integrated circuit design can be divided into stages: system design, logic design, circuit design, layout design, fabrication and testing. More ...
Processor Interrupts
An interrupt is a signal to the processor indicating an event has occurred that needs immediate attention. When an interrupt occurs, the processors normal path of execution is interrupted in order to run a routine to service the interrupt requester. More ...
Network on a Chip (NoC)
NoC (Network on a Chip) is a method of placing a much larger number of processors on a multi-core chip. Much like a regular network, NoC has multiple point-to-point data links that are interconnected by routing switches. More ...
Capacitors in AC Circuits
In an AC circuit capacitors exhibit a property similar to resistance called reactance and cause a phase shift between votage and current. The vector sum of resistance and reactance in an AC circuit is called impedance. More ...
The Microcontroller Memory Map
a microcontroller is a set of resources. Each resource is identified by one or more addresses in an address space. The memory map is a graphic representation of how the resources are associated with addresses. More ...
Basic Arithmetic Logic Unit (ALU) Circuitry
One of the primary functions performed by a computer is mathematics. This article describes some of the logic circuits used to create the Arithmetic Logic Unit (ALU) of a microprocessor. More ...
Fundamental Digital Logic Gates
All the advanced features of the most powerful computers, such as mulicore and parallel processing are done with digital logic. In this article I explain the fundamental concept of digital logic in simple and clear language so that anyone can understand it. More ...
Arduino Microcontroller Development Platform
The benefit of the open source Arduino Microcontroller Development Platform is that the software is free and the hardware is cheap. This makes it one of the cheapest platforms on which to develop prototypes. More ...
