Intel's Core i7 Processors
Core i7 is a family of Intel quad core processors, that is, they have four processors on
a single silicon chip. All four processor cores and all memory caches, including a 64K L1
cache, a 256K L2 cache, and a shared L3 cache are located on one chip. The memory is also
located on the same chip. More ...
Binary Number Representation and Binary Math
Computers perform all of their amazing work with only two voltage levels, one representing binary 0,
the other representing binary 1. This article describes how to perform binary addition and subtraction. 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 ...
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 ...
Simplified Windows Architecture Overview
A simplified overview of the Windows operating system architecture divides it into user-mode and kernel-mode components. More ...
There are five types of circuits; open, short, series, parallel, and series-parallel. Using Ohm's law, along with the reciprocal formula to calculate the equivalent resistance of resistors in parallel, you can calculate the voltage or current in any part of a circuit. More ...
AMD's Phenom Processor
Since 2005 AMD has used the Athlon name for their processors. This changed in 2007
when they released their new processor called Phenom. So we must ask the question;
what is the difference between the Athlon and the Phenom? 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 ...
Interrupt Request Lines (IRQs)
What happens when the CPU (Central Processor Unit) is busy doing something, like defragmenting
the hard disk, and you press a key on the keyboard? An interrupt (IRQ) is a connection between
a hardware device and the CPU. A hardware device uses it's assigned IRQ line to signal or interrupt
the CPU when it needs attention. 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 ...
The AMD Athlon 64 Processor
AMD's Athlon 64 processor, released in September 2003, was their first 64-bit processor
targeted for the workstation market to compete with Intel's Pentium 4. AMD's first
64-bit processor was the Opteron, released earlier in April that same year, targeted
for the server market to compete with Intel's Xeon processor. More ...
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 ...
