G.hn, does it get the crown for in-home networking?

By Nikhil Chauhan The new buzzword in wired networking is G.hn, pronounced as "G dot hn". I know, it does add another word to the alphabet soup of technologies, but I do think that it solves a fundamental lingering problem.Our homes have various types of wiring available today; these constitute power, cable, phone, etc. The problem is that all of…

Busting the Myths Around VxWorks #5: Security

By Bill Graham In reality this isn’t a myth, it’s more of an awareness problem. Our solution for the need for high robustness systems is the VxWorks MILS product. VxWorks MILS is designed to provide Multiple independent Levels of Security (MLS), a security concept that ensures that complete separation is provided between secure and non-secure portions of a system (and…

Addressing Core Issues

By Mark Hermeling A good article from colleague Jens Wiegand on multicore in medical devices. Jens talks about consolidation and innovation, two driving factors in both medical and industrial devices. However, he also points out the flip side of the coin: certification. Virtualization can help provide strong separation on multicore, which makes certification manageable (the article goes into more depth).Jens…

Quit Bugging Me: Memory Leak!

By Mike Deliman A perennial question arises... "Did I find a memory leak in the shell?  See what it does?"This question naturally arises after a customer has been debugging a while, and runs short on memory for some allocation.  They check into it, and they find that when they call certain shell functions, they find memory missing after the call.Here…

Busting the Myths around VxWorks #4: VxWorks reliability

By Bill Graham I don’t think we are promoting the reliability of our products well enough. In particular, a key attribute and value of VxWorks is its reliability. Being a newcomer to Wind River my colleagues here were surprised to hear that the reliability of VxWorks would have been called into question. Being on the inside, of course, I am…

Wind River’s Next Chapter

By Ken Klein It’s been roughly 90 days since Wind River became a wholly owned subsidiary of Intel, and I wanted to take this opportunity to share with you the state of our business and a few personal thoughts of mine in what marks my inaugural contribution to the Wind River Blog Network. Let me begin by saying what an…

A Legacy Of Titans

By Mike Deliman PASADENA, Calif. – NASA's Galileo spacecraft began what would become a 14-year odyssey of exploration 20 years ago this Sunday, Oct. 18. Galileo was humanity's first emissary to orbit a planet in the outer solar system – Jupiter. (Read More) 20 years ago I was just starting to work with a remarkably small, very unix-like kernel from this *tiny*…

Wi-Fi Direct Permeating Personal Area Networking

By Nikhil Chauhan Did you hear it?Wi-Fi Alliance launches a specification called Wi-Fi Direct that allows WLAN (Wireless LAN) devices to connect directly without an Access Point in between. Well, well, this appears to be a war of worlds between the WLAN and Bluetooth camps because this surely will fit the use cases of Bluetooth users. Does this also mean…

Busting the Myths around VxWorks #3: VxWorks and Memory Protection

By Bill Graham A common misconception about VxWorks is that it doesn’t have memory protection. Other forms of this myth maybe that you can only program VxWorks with flat memory tasks and that it doesn't support processes a la Unix. Now I suspect the root of the myth is from the pre-VxWorks version 6.x days and the lack of memory…

Simulation? Virtualization? What’s in a name?

By Emeka Nwafor Check out this great panel round-table conversation about Virtualization & Simulation featuring a great set of panelists from Virtutech, Freescale, Cadence, GreenSocs, and our own Wind River CTO. The discussion touches on a number of important topics, including: the differences between virtualization and simulation the level of abstractions in models and their importance in predicting a system's…
