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 ...
Multiuser Operating System Functions
Some operating system functions like resource allocation, accounting, protection and security exist not for helping the user, but rather for ensuring the efficient operation of the system itself. 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 ...
Processor Interrupts
An interrupt is a signal to the processor indicating an event has occurred that needs immediate attention. When an interrupt occurs, the processors normal path of execution is interrupted in order to run a routine to service the interrupt requester. More ...
The Android Operating System
Android os is similar to Apple ios in that it is a layered stack of software that provides a rich set of frameworks for developing mobile applications. At the bottom of this software stack is the Linux kernal. More ...
Introduction to Microprocessor Programming
Assembly language involves using instructions that are mnemonics called opcodes, along with values and/or addresses in hexadecimal notation. To make learning as easy as possible, we'll first learn how to program a simple microprocessor, the 6502. 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 ...
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 ...
Factors in Choosing an Oscilloscope
An oscilloscope is an instrument used to display the waveform of electronic signals. It draws a graph of the voltage as a function of time. A digital oscilloscope can also store waveforms and perform mathematical analysis of the waveform. More ...
Operating System Process Scheduling Queues
The objective of multiprogramming is to have some process running at all times, to maximize CPU utilization. To meet these objectives, the process scheduler selects a process from a queue for execution on the CPU. 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 ...
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 ...
