CPU Chip Packaging
Over the development time of the computer, several different designs of packaging for the CPU chip die have been used. Each type of packaging has its advantages and disadvantages. This article reviews some common packages that might still be in use. 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 ...
Introduction to Boolean Algebra
Boolean algebra is a system of mathematics in which the values of the variables can take on only one of two values, either 0 or 1. Similar to regular algebra, Boolean algebra can be used to simplify a mathematical expression. Since computer logic is also a system in which the values of the inputs and outputs can take on only one of two values, Boolean algebra can be used to simplify logic circuits. More ...
Operating System Memory Paging
Paging is a memory management scheme that permits a process's physical address space to be noncontiguous. 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 ...
Intoduction to Digital Electronics
The entire field of computer technology relies on transistors. This article describes how transistors are constructed and how modern MOSFETs are combined to make digital logic circuits. More ...
Pi-Top kit - Build Your Own Laptop
Computer hobbyists has been building their own desktop computers since the mid 1980's, but I know of no laptop kits, until now. The Pi-Top is a kit that lets you build your own laptop. More ...
Operating System Process Management
A program is not a process. A program is a file containing a list of instructions stored on disk. A process is an active entity with a program counter specifying the next instruction to execute and a set of resources. A program becomes a process when an executable file is loaded into memory. More ...
Intel's Dual-Core Core i3 Processor
Core i3 is an entry-level 2-core processor using the 32nm Westmere micro-architecture. With a Thermal Design Power (TDP) of 73 watts, the i3-530 is a cool-running chip that doesn't gobble loads of electricity, so those looking for a power-efficient, quiet machine will be happy with it. More ...
Getting started with Raspberry Pi
So you have a Raspberry Pi, or you're thinking of getting one, and you want to know how to get started and how to become a master user of one. More ...
Analog to Digital Convertion with a Microcontroller
Analog-to-digital conversion (or A/D conversion), is an electronic process that converts a continuously variable signal into a digital signal (expressed as a string of 1s and 0s). More ...
The Microcontroller Interrupt System
Events related to peripheral interfaces are asynchronous to the program running on the CPU. The interrupt mechanism allows an external event to temporarily put the normal execution of the microcontroller on hold and force the execution of a specific subroutine. More ...
