AMD's Phenom II Processor
Phenom II is AMD's family of 45 nm multi-core processors and is the successor to the original
Phenom. In the Phenom II, the shared L3 cache increased from 2MB to 6MB. The chip has an
integrated, dual-channel memory controller that supports DDR3 RAM, and 4000MHz HyperTransport technology. More ...
Introduction to the Raspberry Pi
The Raspberry Pi is a tiny bare-bones computer motherboard. You can easily make it into a Linux PC by connecting your own keyboard, mouse, and display. 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 ...
Intel's Sandy Bridge Micro-Architecture
"Sandy Bridge" is Intel's code name for a new cpu core microarchitecture. It introduces
a few new or improved features. The memory controller, the PCI Express controller, and
video circuitry are all located within the processor die and the new "ring architecture"
uses a Last Level Cache between the CPU and graphics cores. 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 ...
Inductors in DC Circuits
An inductor is constructed with a coil of wire. When connected to a voltage source, an inductor resists a change in current flow as it stores energy in its magnetic field, and it can return that energy to the circuit if desired. 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 ...
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 ...
Digital Logic Transfer Characteristics
In the real world, gates don't transfer logic levels instantaneously. The time it takes for electrons and holes to move through the semiconductor material (called propagation delay) in CMOS are less than 100 ps (pico seconds), but there are other delays caused by resistance, capacitance, and inductance. More ...
Capacitors in DC Circuits
A capacitor is a component that can be used to store an electrical charge. A capacitor can be used to create a timer. This time delay can be used to smooth a changing current flow in a circuit, or it can be used to absorb spikes and prevent false triggering of other components. More ...
AMD Sempron Processor
The Sempron replaced the Duron as AMD's budget processor. The socket A Sempron is
basically an Athlon XP with half the cache. The socket 754 Sempron is a cut down
version of the Athlon 64 processor with half the cache. More ...
CPU Cache Basics
After the processor accesses a location in memory, there's a high probability that
the next location in memory that it will access is in the same area of memory. So
to make the computer run faster, a a smaller, faster memory called a "cache" is
placed between main memory and the processor. More ...
