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.

Change Raspberry Pi Default Configuration
If you are a US user of the Raspberry Pi, you will discover that when you type, the characters displayed do not match our keyboard. When you type [shift][#] instead you get the British pound symbol. This is because Raspbian (and NOOBS) defaults to UK keyboard settings. 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 ...
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 ...
Logical Versus Physical Memory Addresses
Computers use logical and physical addresses to access memory locatiuons. The CPU generates logical addresses. At run-time the Memory Management Unit (MMU) maps logical addresses to physical addresses. More ...
CPU Process Memory Address Binding
For a program to run on a CPU it must be brought from files in long-term, non-volatile storage to main memory. Addresses in the source program must be mapped to addresses in main memory. More ...
Priority CPU Scheduling Algorithm
CPU Scheduling deals with the problem of deciding which of the processes in the ready queue is to be alocated the CPU. There are many different CPU scheduling algorithms. In this article we describe priority CPU scheduling. More ...
Learn Assembly Language Programming on Raspberry Pi 400
One of the easiest ways to learn assembly language programming is on the Raspberry Pi 400. The Raspberry Pi 400 is a complete personal computer built into a compact keyboard. More ...
Electronic Circuits Basics
This article's main target is to teach the electronics language to readers that are not familiar with electronics by using a group of rules and simple equations that describe the behavior of every electronic component and the relationship between the components in the circuit. 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 ...
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 ...
The Use of SOI (Silicone on Insulator) Wafers in MEMS (Micro-Electro-Mechanical Systems) Production
The main advantage of Silicone on Insulator (SOI) technology is that they enable the manufacture of smaller devices. The manufacturing process optimizes the efficiency of transistors and allows chips to be packed close together, resulting in a greater yield per wafer. More ...
