Blog Post:Debugging with printf() or not ...

Colin Walls — Mon, 08 Apr 2013 16:22:39 GMT

My colleague Richard Vlamynck [who has been a guest blogger here] and I were discussing tracing and debugging. Like me, he has been doing software for a few years. Hence, when we considered tracing and instrumenting code, he commented “It used to be easy to see what effect trace statements had on your program because, as you put more or less trace cards in your Fortran deck, you could visually

Blog Post:Web seminar

Colin Walls — Tue, 23 Aug 2011 15:00:27 GMT

Just a quick “heads up”. If you are interested in the selection of an operating system for embedded applications [a topic I discussed briefly here] you might like to attend a Web seminar that I am presenting later this week. The session will be less than one hour, including live Q&A. The live session will be on Thursday at 9:00 Pacific and an archive recording will be available after

Blog Post:System power

Colin Walls — Mon, 06 Jun 2011 22:39:08 GMT

I have raised the subject of embedded device power consumption before and I will again, as this is becoming more and more of a hot topic [no pun intended]. As I have touched upon on a previous occasion, power consumption is no longer purely a hardware - the software can have a significant effect. There are obvious ways that software has an influence: code efficiency, control of system voltage and clock

Blog Post:Introducing OpenMCAPI

Hollis Blanchard — Wed, 30 Mar 2011 18:50:22 GMT

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

On-demand Web Seminar:CPU-to-CPU Communications in Multicore Designs

Wed, 09 Mar 2011 00:21:06 GMT

Embedded designs incorporating several CPUs - either multiple cores on a chip, multiple chips on a board, or a combination of the two - are becoming increasingly common. It's no secret that software development for multicore systems has its challenges, but fortunately, the industry is working towards sorting out the key issues.

Blog Post:A different angle on multicore

Colin Walls — Mon, 14 Feb 2011 19:02:48 GMT

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.

Blog Post:Embedded Linux - why?

Colin Walls — Mon, 23 Aug 2010 16:19:55 GMT

I have pondered before the appropriateness of Linux for embedded applications. My initial stance was clear enough: I could see very little sense in it. Why use a desktop operating system in such a completely different context? Over the years, the popularity of embedded Linux has increased, the technology of embedded systems has moved on and I have reappraised my views accordingly. With Mentor Embedded

White Paper:A Case for MCAPI: CPU-TO-CPU Communications in Multicore Designs

Mon, 16 Aug 2010 07:00:00 GMT

This paper offers an introduction to the MCAPI standard and illustrates its implementation within the framework of the Mentor Embedded™ Nucleus® operating system and Linux® open source software.

Embedded designs incorporating several CPUs – either multiple cores on a chip, multiple chips on a board, or a combination of the two – are becoming increasingly common. It’s no secret that software development for multicore systems has its challenges, but fortunately, the industry is working towards addressing these key issues and challenges. This paper begins with a brief introduction on multicore design, covering symmetrical multiprocessing (SMP)compared with asymmetrical multiprocessing (AMP) and the software implications, such as the use of multiple operating systems.

The primary focus of this paper is on the emerging standard from the Multicore Association, the Multicore Communications API, or “MCAPI.” MCAPI provides a rational way for software developers to implement communication between cores, even between multiple disparate operating systems.
