Kick-Starting the VxWorks 6.9 64-bit Port with Simics

By Jakob Engblom Wind River just released the world's first 64-bit RTOS, Wind River VxWorks 6.9 for the 64-bit Intel x86 Architecture. This is a great achievement by the VxWorks team, and I am proud to say that Simics played a role in the development of the 64-bit port of VxWorks. Simics was used throughout the development in a variety…

Rendezvous with a Rock

By Mike Deliman MESSENGER spacecraft is approaching it's rendezvous with Mercury.  After flying for over 2400 days, in a little over 24 hours (from writing this)  MESSENGER will maneuver into orbit, the first time a satellite has orbited Mercury.  We hope to learn a lot about the composition of the surface and effects of solar weathering of the surface.  And there's…

Integration and Testing the Integration

By Jakob Engblom The US National Highway Traffic Safety Administration (NHTSA) recently released a deep report into last year's issue with "unintended acceleration" on certain Toyota cars. They actually employed a team from NASA who analyzed the throttle control software using a wide range of cutting-edge tools. Reading their report gives a good idea for how embedded control software is…

Remarkable

By Mike Deliman "Space... the final frontier" is how the pre-recorded message from NASA to the crew of Discovery started this morning. This afternoon while covering the final departure of Discovery from the ISS, the newsman said "Remarkable - a remarkable bit of technology and a lasting mark on history" - or something to that effect. I thought "Remarkable" - that's a…

Scalability: the key to product line success

By Bill Graham An important requirement for an RTOS such as VxWorks is scalability. What this really means is being usable in many different types of devices, from small memory constrained, low power devices (possibly battery powered, hand held, mobile) to large scale systems, multiple nodes networked together, possibly using multicore in a multi-OS environment. Scaling down is equally important…
