Solid State Disks Creating Buzz One Notebook at a Time
By Joanne De Peralta, BiTMICRO
The release of Apple's MacBook Air, Lenovo Thinkpad, and Dell Latitude Notebooks — all equipped with solid state disks — have created a strong buzz in the computing industry. Debates of whether or not the era of SSDs has finally arrived have stimulated activity in quite a number of forums. The […]
ZigBee Mesh Networking Radio Comes of Age?
By Ollie Smith, Telegesis
ZigBee has been a bit of a buzz word among engineers looking for wireless solutions over the past eighteen months or more. ZigBee low power mesh networking radio technology is its more accurate — if somewhat cumbersome — description for those who have yet to encounter it. But despite being a prominent […]
SCADE 6: Requirements Driven, Model Based, Safety Focused
Avionic, railway, and high-end automotive systems have become too complex to develop and coordinate without the assistance of a design environment that connects all of the developers through their participation in the execution of the engineering process. The more efficient solution in this case is to use a model-based design tool. The adoption of Model-Based […]
Integrated Recovery Solutions Make Sense for Both the Manufacturer and the Customer
Disk Imaging Recovery Software with Copy-On-Write Snapshot Technology Lessens the Burden of "Digital Disasters"
By Don Lewis, FarStone Technology
When mishaps, malfunctions, failures and crashes take down a computer system, the potential for lost data and increased calls for Technical Support assistance can cause a "digital disaster" that affects both computer system builders and end users alike. […]
Blending Asymmetric and Symmetric Multiprocessing with a Single OS on ARM11 MPCore
By Masaki Gondo, Director of Engineering, eSOL Co., Ltd.
Synopsis
ARM11 MPCore is an excellent multicore processor, appropriate for both SMP and AMP. Many embedded system designs already uses AMP model, either on chip or off chips, so unforeseen design challenges are limited for software developers using AMP model with MPCore. On the other hand, the increasingly […]
Universal Graphics-on-Module Standard (UGM)
Developers of applications with sophisticated graphics (for example: medical and industrial imaging, gaming and entertainment machines, POS/POI terminals, commercial outdoor broadcasting, public facilities and high-end residential gateways) have always had a problem with graphics. If they were looking for powerful graphics cards with long-term availability for their embedded designs they found that such cards simply […]
Debunking Misconceptions in SSD Longevity
Aside from flash memory prices, the write endurance limitation of flash memory is probably one of the remaining impediments to the widespread application of non-volatile solid-state storage in the enterprise. Flash SSD critics have long harped on this apparent "weakness" that remains a thorn on the side of SSD manufacturers despite the development of advanced […]
Flash Drives to Cache in on Windows Vista
By Leilani Junghan, BiTMICRO Networks
The launch of Windows Vista, Microsoft's latest OS, in the last quarter of this year may change the computing landscape. One of its intriguing features called ReadyDrive requires the use of hybrid drives. Strictly speaking, this technology centaur is half hard disk drive (HDD), and half solid state disk (SSD) drive. […]
Size Drives Solid-State Flash Disks
By Joanne De Peralta, BiTMICRO Networks
Next to price, capacity has been among the top issues that level out solid-state flash disk with magnetic hard drives. If not for those two factors, solid-state disks would be the runaway winner offering ruggedness, speed and small footprints. However, recent developments are starting to change the conditions.
According to the […]
How to Debug Linux Kernel and Applications
By Tito Borovski, Ronetix
Introduction
The increasing popularity of high-speed 32-bit ARM based microcontrollers allowed Linux to enter the world of embedded devices. That is why the need for debugging its kernel and applications have become essential. Since Linux is a true multi-process operating system, it utilizes a Memory Management Unit (MMU) to give each process a […]
Flash SSDs Go Beyond the Battlefield
By Joanne De Peralta, BiTMICRO Networks
Flash solid state disks (SSDs) have undoubtedly gained a strong foothold in the military and enterprise markets. Its capacity to withstand extreme conditions made it fit for on and off ground military operations while speed has been its passport to the enterprise market. Right now, SSDs are moving past these […]
Developing Better Communications Systems with Noise Reduction and Echo Cancellation
By: Nathan Blundy, NCT (Europe) Ltd
Introduction
It is estimated that over a third of the world's population spend time talking on mobile phones. The quality of that communication experience very much depends on the clarity of the voice that is heard at each end of the conversation. In an increasingly noisy world, it is easy to […]
