The Advent of Multicore MILS

It's been a rather long time since my previous blog post. I intended to post a blog before Christmas about our partner Curtiss-Wright's news release about VxWorks MILS support on the VPX6-187, but I simply ran out of time! So here it is as my first blog post of 2013. The Curtiss-Wright press release was actually quite a game changer.…

Avionics 2012 report

I've just got back from the Avionics Europe 2012 conference and exhibition which was held in Munich. The theme of this year's conference was 'Common Sky: Operating in One Air Space' focussing on the growth in air traffic across Europe, the challenges arising for air traffic management and navigation, and the development of SESAR air traffic management technologies. I was…

Avionics 2012 conference

It's been a long time since my previous blog, as unfortunately I've been engrossed in a number of projects! However, I have just got time to mention that I'm really looking forward to the Avionics Europe conference in Munich on 21-22 March. The conference programme is pretty packed, covering cockpit avionics and technologies for civil and military aircraft; and aircraft,…

Fun with VxWorks MILS 2.1

It’s been a while since my previous blog, as I have been rather preoccupied with responding to a number of RFPs. However, I’ve managed to find some time to work on some demos for VxWorks MILS 2.1, which has been fun. VxWorks MILS 2.1 introduced support for Wind River Linux as a Guest OS (VxWorks Guest OS and High Assurance…

Farewell to Del.icio.us

I was disappointed to read in TechCrunch this morning that Yahoo has decided to shut down the Del.icio.us social bookmarking website (or should I say service?). I started using Delicious a few years ago after I had become fed up trying to organise my website bookmarks. I often want to bookmark A&D news stories, blog articles, technical papers and standards,…

High Assurance Systems Development Using the MILS Architecture

When I'm discussing VxWorks MILS with Wind River customers, I often find that in addition to wanting hear about the capabilities and features of the platform, they are also interested in the rationale for the MILS architecture and the implementation approach for the VxWorks MILS separation kernel. So, I've recently written a technical white paper "High Assurance Systems Development using…

National Cybersecurity Strategy

On Monday, the UK government published its new national security strategy (PDF). This outlines the current and emerging security threats to the UK national interests, ranked by priority based on likelihood and impact. What caught my attention was the fact that the Tier 1 (highest priority) threats include:   'Hostile attacks on UK cyber space by other states and large…

VxWorks MILS 2.1 Platform hands-on

Last week, I visited Wind River headquarters in Alameda, California, to learn about VxWorks MILS Platform 2.1 and to get hands-on experience with the release. I had been looking forward to the trip, as the 2.1 release adds some significant new capabilities: Wind River Linux as a guest operating system and the new High Assurance Network Stack (see Bill Graham's…

EGNOS Satellite Navigation System Safety Certification

In case you missed it, yesterday Wind River announced that VxWorks has been selected for the European Geostationary Navigation Overlay Service (EGNOS), and has been chosen to run the Integrity Processing Facility (IPF) check set. The IPF, developed and delivered by Logica, is the crucial element that validates the information broadcast by the satellites to safety-critical users such as aircraft…

Multicore called up for active service

There's an interesting editorial column 'Multicore Processing Becomes the New Mainstream' in the latest edition of COTS Journal. Jeff Child discusses how multicore processors, after becoming all pervasive in the desktop and server market, are now becoming the norm for embedded aerospace and defence systems. He also shares some insights into why the transition to multicore is necessary, and provides…
