Interview with Girish Venkatasubramanian

By Jakob Engblom After my blog post on Academic Simics earlier this Summer, I got a very nice reply from Girish Venkatasubramanian of UFL. Turned out that he and his group was doing some really interesting and exciting stuff with Simics, researching into Hypervisor architectures and hardware support. Having been a PhD student myself, I can certainly appreciate the excitement…

Wind River and IBM Attack Software Quality

By Paul Henderson As I've mentioned before, we've been working with IBM Rational for some time around quality management automation. Both companies see the skyrocketing software content and architectural complexity in the embedded device market as creating a tipping point where companies will not be able to continue with business as usual. Product development teams will need to take a…

Type 1 versus Type 2 Hypervisors

By Mark Hermeling I have always found the difference between Type 1 vs Type 2 hypervisors rather uninteresting. In short, a type-1 hypervisor is a hypervisor that has direct access to the hardware, where a type-2 hypervisor executes inside an operating system. Most hypervisors are type-1 hypervisors, including IT hypervisors such as VMWare, Xen, KVM and such. Type-2 hypervisors are applications…

VxWorks in Education: University of São Paulo, Brazil – Part 3

By Bill Graham In the third and final part of my interview with Professor Glauco Caurin we discuss multicore and virtualization and why they are working with us on their research projects. Q: Are your students learning about multi-core processors  and programming? What about multi-OS systems including virtualization, i.e.  systems that have more than one OS on a single processor?…

Freescale on Multi-core and Virtualization

By Mark Hermeling Two good blog posts from some of my colleagues at Freescale. One on Heading Into Hyperspace: Hypervisor and Multi-core design by Jim Trudeau and one by Rob Oshana on the Top 3 Keys to Multi-core software development. Jim talks about the multi-core aspects mostly from Freescale's P4080 perspective, an elegant, powerful and very popular processor in the networking…

Primary Virtualization Use Case

By Mark Hermeling This topic invariably comes up when talking to customers, unfortunately, there is not just one, but several primary use cases. There are multiple ways to look into the various use cases. The one I like best is to look at generic drivers. An alternative is to look at actual usages in the various industries.

It’s Time for Testers to Step Up

By Paul Henderson RTC Magazine recently published an article that I wrote called "Time to Rethink Software Testing for Embedded Devices". In it I describe some of the new techniques that are possible, and I believe necessary, to delivery high quality device software for embedded devices. When staying 'positive' doesn't pay Getting negative with white box testing Focusing on the…

Test Driven Development Meets Continuous Integration

By Paul Henderson In my last posting I mentioned I'd be running a webinar with James Grenning on Agile testing. James is a recognized expert and frequent speaker on the topic of software development and one of the original authors of the Manifesto for Agile Software Development. We talked about the case for agility where today's embedded software projects are…
