It has been a rather long time since my previous blog post. I intended to post a blog before the holidays regarding our partner Curtiss-Wright's announcement 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 new release was actually quite a game changer. To the casual reader, it may just appear to be about the release of another board support package (BSP) on a leading-edge COTS processor card, but the fact that this BSP supports multi-core for a MILS architecture is what makes this announcement so significant.

When the MILS software architecture was proposed in 1984 by the computer scientist Dr. John Rushby, microprocessors at the time were inherently single-core, and computing performance advances were being driven by clock speed increases and die size, at a rate following Moore's Law.
