Multicore Programming
A recent trend in system design is to place multiple computing cores on a single chip. Each core appears as a separate processor to the operating system. We call these multicore or multiprocessor systems. More ...
How Computer Memory Works
Every program being executed and every piece of data being manipulated must be copied from a storage device, such as a magnetic disk, into main memory. It's important to understand the basic types of memory. More ...
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 ...
Basic Computer Architecture
Computers today, even that PC on your desk are unbelievably complex. You can't understand computers without an understanding of the basics. In this article I explain basic computer architecture in simple, basic terms. More ...
The Motherboard Chipset
Because the chipset dictates the bus speed, type and amount of memory, and the type and number of I/O ports, much of a computer's performance is determined by its chipset. More ...
Microcontroller's Parallel I/O System
The most common way for microcontrollers to interact with the outside world is the The digital I/O lines. More ...
The AMD Athlon 64 X2 Processor
The Athlon 64 X2 is the first dual-core CPU manufactured by AMD.
It is essentially two Athlon 64 cores on one die joined together with additional control logic. The cores share one dual-channel memory controller. The benefit of dual-core processors is their ability to process more software threads at the same time. However, many programs are written with only one thread. More ...
Online Color Coded Resistor Calculator
To determine the resistance value of a color-coded resistor, select the colors matching each band from the drop-down lists. 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 ...
AMD's Phenom Processor
AMD released the first Phenom processor in 2007. Unlike Intel's Core 2 Quad processors, which are a multi-chip module (MCM) design, AMD's Phenom processors had all cores on the same silicon die. 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 ...
Microprocessor Registers
To a large extent the operation of a microprocessor involves loading, transferring, and manipulating the contents of registers. In this article you learn about the functions, and purposes of the register set of the Intel 8086 microprocessor. More ...
