Migrating to Multi-core using Embedded Virtualization

By Mark Hermeling So, let's assume that you are currently on a single-core board and you would like to explore the possibilities of delivering a next generation device using multi-core technologies. There are a lot of different ways to approach this. The most elaborate involve doing an architecture study into ways in which you could evolve your current device architecture.…

Wind River Network Acceleration Platform Wins Best Software Award

By Jessica Schieve Last night I had the pleasure of attending the 2010 ATCA Summit Best of Show Awards ceremony where Wind River was presented the Best Software award for its Wind River Network Acceleration Platform.   This is a major accomplishment for a industry solution that was launched less than a year ago. The panel of judges included industry editors as well as…

Embedded Virtualization in Gaming

By Mark Hermeling A few weeks ago I found myself in the Hard Rock Hotel in Las Vegas. My reason for being there was a seminar that Wind River was organizing together with Intel and AVNET specifically focussed on companies that build gaming. The main topics were graphics, manageability and of course, virtualization. I am always eager to fold real-life…

IMA on Simics: An Interview with Tennessee Carmel-Veilleux

By Jakob Engblom After Summer, I have been in contact with Tennessee Carmel-Veilleux at the École de technologie supérieure in Quebec, who has been doing some really cool work with Simics.  Tennessee has learnt Simics very quickly, and has been very clever in how to apply Simics to the research problems he has encountered. In this interview, he tells us…

Embedded Virtualization and Multi-Core

By Mark Hermeling VDC has released a recent report showing that multi-core is making fast inroads in embedded systems and we are seeing that at Wind River as well. There are exciting new possibilities with these chips, we have never had this much processing power in such small packages. Take for example Freescale's new P4080 chip, 8 cores, 2 memory…

Intuitive & Efficient Debug of Multi-core Systems

By Brian Finkel I reflect on a recent visit with my 84-year old Aunt Honey. As you might expect, she is not an avid cell phone user. She wanted help entering contacts into her phone. She has a basic phone so we had to enter text using the “9-up” keypad. Her objective is to make phone calls by selecting someone’s…

Devices! Devices! Devices!

By Mark Hermeling That is what embedded systems is all about: handling devices. An embedded software system has input devices and output devices and some amount of software running on operating systems, running on hardware that turn input into output. The trick is to handle the input in a fast an deterministic way and generate output in a fast and…

Variable and Deterministic

By Jakob Engblom A virtual platform like Wind River Simics is generally designed to be deterministic. Determinism brings a host of benefits to users (repeatability of bugs, reverse execution, bug transportation, etc.), but is also easily misunderstood. Quite often, users fear that they will lose an important "feature" of a physical machine - its built-in variation across runs of the…

Test Automation Meets Simulation

By Paul Henderson I'm seeing increasing interest from many companies in using simulation environments with test automation systems to accelerate the testing process. Specifically, putting Wind River Test Management together with Wind River Simics is getting creative juices flowing in industry thought leaders. Why? Well, development teams have started to realize the benefits of simulation systems for speeding and validating system…

Transporting Bugs with Checkpoints

By Jakob Engblom I have a paper about "Transporting Bugs with Checkpoints" to be presented at the S4D (System, Software, SoC and Silicon Debug) conference in Southampton, UK, on September 15 and 16, 2010. The core concept presented is to leverage Wind River Simics checkpointing to capture and move a bug from the bug reporter to the responsible developer. It…
