Matt Radochonski At Embedded World in Nuremberg from Feb 25-27 we will have a number of demos to show off at the Mentor Embedded Booth.  Come join us in Hall 4, Booth 4-422 to see and learn more about: Delivering Powerful IoT Systems Connected devices range from wearables, to smart meters, to smart appliances, to connected vehicles. Design of these IoT devices requires minimizing memory footprint, seamlessly connecting … Read More

Kamran Shah There are a number of heterogeneous multicore SoCs being introduced including the Vybrid platform from Freescale and the Jacinto 6 platform from Texas Instruments. At CES in January 2014 we demonstrated how the communication between Cortex M4 and Cortex A15 cores on the TI Jacinto 6 can be implemented using rpmsg. The two videos below show this demonstration in action. The first video illustrates how … Read More

Colin Walls In the light of recent announcement of Mentor Embedded Hypervisor and discussions about embedded hypervisor technology, I am pleased to have another opportunity to host the ramblings [his word] of my colleague Faheem Sheikh. I would question his implying that it is easy to make a perfect cheese omelette from a recipe … An oft-cited analogy for software working out-of-the-box (OOTB) is that of … Read More

Colin Walls I recently discussed hypervisor technology and how it is being applied in embedded systems. This coincided with Mentor Embedded’s announcement of Mentor Embedded Hypervisor. I described what a hypervisor is and something about how it works, but I did not address applications for hypervisors – where they are used and why. The initial announcement that I quoted, was focused on using hypervisors … Read More

Colin Walls My busy two week conference period is now behind me and, having had a bit of R&R in the meantime, I have had a chance to reflect on some of my experiences and impressions of the three events: ARM TechCon, ECS and IP-SoC. If you attended any of these events, please email or comment to share your thoughts. If you would like copies of any of my materials, please email … ARM TechCon, Santa Clara, … Read More

Embedded hypervisors

Posted by Colin Walls

Colin Walls Some technologies, it seems to me, should not really exist. They do, however, because they address a specific need. Typically, such technologies stretch something to make it perform in a way that was not originally intended. An example would be the fax machine. In a paper-based office environment, there was a frequent need to move documents from A to B. Initially, this resulted in the mail. But fax … Read More

ARM TechCon

Posted by Colin Walls

Colin Walls As I outlined recently, I am attending a number of conferences in the next couple of weeks. The first one, next week, is ARM TechCon in Santa Clara, CA. This event spans 3 days – 29-31 October. The conference itself covers all 3 days; the exhibition is just days 2 and 3. Each year this event seems to expand in size and scope and I have more things to do there … Mentor Graphics has a significant … Read More

big.LITTLE

Posted by Colin Walls

Colin Walls From time to time, a concept or some terminology pops up and suddenly everyone is talking about it. That is usually the point when I think “I wonder what that is all about.” and start to investigate. That is what happened with ARM’s big.LITTLE concept. As a C programmer at heart, any terminology that uses the case of letters in an odd way gets my attention – and big.LITTLE is … Read More

I recently wrote about the importance of being able to visualize trace data to make sense of all the information that we can now capture with LTTng 2.0 We recently received the results of a customer survey where we got some good feedback on areas you’d like to see us increase our development efforts. Debug tools, multi-core design tools and profiling tools were near the top of the list. This is

On my quest to continue to learn more about embedded systems development I was able to attend LinuxCon 2012 One of the sessions I attended was an update by Mathieu Desnoyers (author and maintainer) on LTTng 2.0 The Sourcery Analyzer trace and analysis tool from Mentor Embedded makes use of LTTng and I’m in meetings where we discuss the benefits of LTTng 2.0 so I was happy to have gotten an overview

Introducing OpenMCAPI

Posted by Hollis Blanchard

Hollis Blanchard

Mentor recently shared OpenMCAPI, our MCAPI implementation, with the world under an open source license (BSD). We’re proud of it because it was especially designed for portability, and while it’s sophisticated enough to offer advanced features like asynchronous communication, it’s simple enough that it can be easily understood and deployed on low-resource embedded systems. So what

Russ Klein As Yogi Berra once said, “It’s déjà vu, all over again.” I was out at a customer helping them debug a multi-core system. Unlike my Sudoku solver, this was not a multi-threaded SMP application. The customer had 4 processes, each running on a different core and specifically tied to that core. While all the programs were running under the same operating system – the designer did not rely on the OS to … Read More

Multicore is a hot topic at the moment. The subject crops up in numerous articles and I have written about it before. Surveys suggest that, before long, more than half of embedded designs will be implemented using multiple CPUs. There are broadly two hardware architectures: homogeneous multicore, where there are numerous identical cores, and heterogeneous multicore, where the cores differ in architecture.

I was recently asked to participate in a “panel” article in a UK electronics publication. The topic was the apparent decline importance of hardware design, over software design, in embedded systems. An interesting subject - I needed to be careful what I said, as I work for a company where 90% of my colleagues are hardware design specialists! The final piece can be seen here. I was sent a

Russ Klein I never cared for really long blog entries, so I’m splitting this up into a couple of posts. If you missed my last post you’ll want to go back and read it – or you’ll probably be hopelessly lost as we dive into my multi-core Sudoku solving dilemma. As you’ll recall, last time I took my clever Sudoku solver and ran it on an 8 core PPC design, and found I got a 3 X speed up. When I looked into why, it … Read More
