From System Design to Certification: Wind River Helps Rockwell Collins Reduce the Risk of Multi-core Certification

By Paul Parkinson RTCA DO-178C / EUROCAE ED-12C safety certification is a crucial step for safety-critical avionics software programs, but for many program managers and software leads it still poses significant risk, especially when using multi-core processors. This risk is mainly due to the fact that certification authorities have not yet issued formal guidance or policy on multi-core certification. Although…
Multicore Certification at SAE Aerospace Systems and Technology Conference 2016

Multicore Certification at SAE Aerospace Systems and Technology Conference 2016

By Alex Wilson As I mentioned in my last blog, this year’s SAE ASTC had the theme “Innovation in Propulsion Technologies and Intelligent Aircraft Systems” and took place in Hartford, Connecticut, and was hosted by United Technologies, with further sponsorship from Boeing and TTTech. For Wind River, the main discussion of interest was around certification of multicore devices, and for…
Simics 5 Multicore Accelerator – Boosting Performance, Adding Parallelism

Simics 5 Multicore Accelerator – Boosting Performance, Adding Parallelism

By Jakob Engblom One of the headline news of Simics 5 is Multicore Accelerator. With multicore accelerator, we can use a multicore host to simulate a tightly-coupled multicore target. Since the launch of Simics 4.0 in 2008, Simics has been able to simulate multiple discrete target machines or racks on multiple host cores, and Simics 5 takes this to the…
Multi-core is Ready for Takeoff

Multi-core is Ready for Takeoff

By Joe Wlad Over the past two years, there has been an upswing in adoption of multi-core silicon for safety-critical applications. Previously, customers were reticent about predicating new safety designs on multi-core silicon, but in the past year we’ve seen two changes that have compelled designers to reconsider their positions. First, both EASA and the FAA have released guidance related…
Simics Unleashed – Applications of Virtual Platforms

Simics Unleashed – Applications of Virtual Platforms

By Jakob Engblom "Simics Unleashed - Applications of Virtual Platforms" is the title of the latest issue of the Intel Technology Journal (ITJ). The ITJ issue on Simics is approximately 200 pages long, and contains 11 articles from Wind River, Intel, and academia. It covers a wide range of Simics uses, including such diverse topics as very large cluster simulation,…

A Great Win for Wind River in Network Innovation

By Jessica Schieve Wind River Intelligent Network Platform just won the Top Embedded Innovation Award of 2013 from Embedded Computing Design magazine. Wind River Intelligent Network Platform, a high performance data plane solution for packet acceleration and deep packet inspection, is able to provide the right combination of innovation that delivers a comprehensive solution for packet performance and network intelligence.  There is some…

Back to Reverse Execution (Video)

By Jakob Engblom  Simics reverse execution and reverse debugging is a unique and very powerful feature of the simulator. In this blog post and accompanying video, we will look at what exactly it is you can do with reverse execution in Simics. It is not just a matter of running backwards to a breakpoint or stepping instructions (pick up my 2012 S4D article for…

Reliability….the key constant in network transformation

By Jessica Schieve  Wind River recently conducted a webinar on the topic of network transformation and the growing trend around building greater intelligence.   The webinar discussed the results of a survey we commissioned through Light Reading exploring the different facets of network intelligence: packet acceleration, content inspection, flow analysis and traffic shaping, and network virtualization.  It was one of our…

VxWorks: Delivering on the Promise of Multicore

By Bill Graham Wind River had a big week on the multicore front which included a significant presence at last week’s Multicore Developer Conference. In addition to keynoting the event, Wind River delivered two presentations on making the most out of multicore hardware platforms.  A key takeaway from the event is that the hardware has come a long way --…

Securing Critical Infrastructure with MILS

By Paul Chen On February 12, the White House released the Presidential Policy Directive 21 (PPD-21), Critical Infrastructure Security and Resilience. The DHS website describes PPD-21 as “advancing a national policy to strengthen and maintain secure, functioning, and resilient critical infrastructure.” Sixteen different critical infrastructure sectors are identified, including: Chemical, Communications, Energy, Financial Services, Healthcare and Public Health, Food and…
