2010 Is The Year Of Embedded Virtualization

By Mark Hermeling I believe that 2010 will be the year of embedded virtualization, all the signs point in the right direction. It always takes a while for new technology to grab the imagination of embedded device developers. Embedded developers are traditionally a conservative bunch, however, the benefits of virtualization can not be ignored, even by them.Continue Reading >>

Quit Bugging Me: Revalidated

By Mike Deliman One day, I get this phone call. "We're working with the system, we see the calls that update the exception handlers early on - connecting the clock routines, etc. Then not very much farther on we see the system has run past where tasking should be running but it's not.  When we check, we're not getting any…

A Decade at Wind River

By Paul Parkinson On Wednesday, it will be exactly ten years since I joined Wind River. I was thinking about this on my flight to San Francisco on Saturday, and as well as wondering how I long I've spent watching the VxWorks boot loader counting down to zero on the serial console over the years, I was also reminiscing about…

Systems Huge and Really Tiny

By Bill Graham "Diverse" is certainly as word that applies to embedded systems. In fact, it's difficult to really define embedded systems because they can be a windshield wiper controller, a home theater remote control or an Internet backbone switch that handles gigabytes of data per second. VxWorks has been used in all of these types of systems and can…

It’s All About the Evidence

By Bill Graham An important distinction that gets drilled into people new to safety critical systems and certification of said systems is the difference between "certified" and "certification evidence." When certifying a safety critical system to a very strict standard such as DO-178B, the system as a whole is certified not individual components such as operating systems or middleware. Verification…

Do You Design Flight Software?

By Mike Deliman Normally I don't like this blog to sound like a marketing microphone, BUT... once in a while something comes along that's Worth It.  I'll keep it short and sweet.Next month, Larry Kinnan will be running a web presentation about how VxWorks 653 OS is used in the Boeing 787 Dreamliner.   Click here for more information.

VxWorks is Helping Power the Next Generation of Wireless Networks

By Bill Graham You are probably wondering what an RTOS has to do with wireless networks. Well, a lot, actually.  VxWorks is used extensively in telecom/datacom infrastructure including 3G and next generation networks 4G, LTE (Long Term Evolution) and WiMax. As you have likely heard, the current 3G networks are straining from the demand from new wireless smartphones such as…

Getting Shipped Products Fixed; Service and Repair is Not the Only Option

By Bill Graham We intuitively know that defects in the field are much more expensive than those found in development. In fact, the difference is bigger than you think. If you find a bug in-house you save orders of magnitude in time and money. Unfortunately, the occasional defect does find its way out into the a shipping product and when…

Sand Trap

By Mike Deliman Spirit Rover is heading to her sixth anniversary on Mars, but it looks like she'll have to sit the dance out. Spirit has been trapped, basically high-centered on a hard spot surrounded with flour-like soil. Some surprising test results show that one of the wheels we thought was jammed has some slight function, but the bad news…

Article: Virtualization for Network-based Multicore Telecommunication systems – System Requirements

By Mark Hermeling Found a great article discussing the needs of virtualization in the telecom space. The blog posting provides a good overview of technical capabilities that are needed for a virtualization layer in the multicore space.I agree with many of the points that the author brings forward: Isolation, separation, performance (both algorithmic as well as I/O), size, stability, inter-VM…
