Intel's Core 2 Processors
Intel's Core 2 processors, released in July of 2006, are based on the Core microarchitecture, a dual core design using a 65nm manufacturing process to put 291 million transistors on a 143 square mm die. Each core has its own 64KB L1 cache. The two cores share an L2 cache that can be either 2MB or 4MB. 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 ...
Microcontrollers
A microcontroller is an IC that contains a microprocessor as well as RAM, ROM and general I/O ports. Engineers design microcontrollers into specific-purpose devices such as microwave ovens, cars, washing machines, refridgerators, and even space probes. More ...
The Microcontroller's Asynchronous Serial Interface
An Asynchronous Serial Interface sends data one bit at a time, as apposed to a parallel interface which send one byte or one word at a time, and asynchronous means it sends them when its ready, without reference to a clock signal. More ...
Simplified Windows Architecture Overview
A simplified overview of the Windows operating system architecture divides it into user-mode and kernel-mode components. More ...
Basic Computer Architecture
Basic computer architecture refers to the structure of a computer system and comprises its hardware, firmware, and software. Hardware consists of the physical components in computer architecture. The main hardware components of the computer architecture include the CPU, memory, and bus. More ...
Stored Program Architecture
Almost every computer system ever made is based on the stored program architecture designed in 1945 design by the mathematician John Von Neumann. He described a system where data and instructions would be stored in memory. More ...
Program Flow Charting
Depending upon the language used, program code my be difficult for humans to read and understand. However, one type of programming that is very easy to understand is flow charting. 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 Processes
An Operating System Process is a program in execution. It includes the value in the program counter and in the processors registers. A process also includes a stack, data section, and a heap. 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 ...
Challenges of Programming Multicore Systems
Operating system designers must write scheduling algorithms that use multiple processing cores and application programmers, mustmodify existing programs and design new programs that are multithreaded. More ...
