24 July, 2017

An increasingly important factor in embedded software development is power management. Historically, this was a solely hardware issue; that has all changed in recent years. Once the software has the ability to take control of factors that affect the system’s power consumption, it is logical that it should exercise that control in an efficient way.

Much is said about the implementation of power management software, but less is said about its design … Read the rest of this entry »

Next week is the Embedded Conference Scandinavia [ECS], which takes place in Kista – a suburb of Stockholm, Sweden.

This is the foremost embedded event in the Scandinavian region and I have visited and presented there numerous times. This year I have the privilege of being invited to present 4 papers … Read the rest of this entry »

Each Fall, just before the weather becomes too horrible, I get to attend ECS [Embedded Conference Scandinavia] in Stockholm, Sweden. It has become a good event for embedded developers in that area and I am pleased that my paper submissions seem to result in a couple of acceptances each year.

This year, I assume ECS will be in 6 months or so, but the organizers are inaugurating a new event … Read the rest of this entry »

I am continuing my catch-up process of cataloging embedded software articles that I have had published on This time they cover the influence of software on power management, using a memory management unit, all about the C/C++ keyword static and the basics of multicore … Read the rest of this entry »

When I made the very first posting  to this blog, more than five years ago, I made the observation that the world of embedded software is very fashion conscious. I certainly do not mean that embedded software developers are renowned for their dress sense! I am talking about the way that a particular technology is really “hot” at any one time … Read the rest of this entry »

Next week, the world’s largest event, dedicated to embedded systems, takes place: Embedded World is on Tuesday-Thursday 25-27 February in Nuremberg, Germany. I have attended this show for many years and talked about it here. This year is no exception.

Mentor Embedded has a strong presence at the show in Booth 4‐422 in Hall 4, with numerous demos to see and members of the team to meet. I will be around on the booth for much of the show – do come along and say hello.

Embedded World is much more than a trade show – there is a growing conference too. The sessions are strictly vetted to ensure a good technical content. A number of members of our team have papers to present. This year, I have two:

  • Tues 25 Feb 14:00-14:30 – session 05 – “Power Management in Embedded Systems”
  • Thurs 27 Feb 11:30-12:00 – session 20 – “Interprocessor Communications and MCAPI”

Do come along if you are at the conference. If you would like copies of my presentations after the event, please email.

You can see a complete run down of Mentor Embedded’s presence, which outlines all the demos and lists all the conference papers.

Power management is a hot topic – or maybe that should read “a cool topic” – among embedded developers of late. In the course of a recent conversation on the subject, I realized that there are, in effect, three kinds of power saving procedure that embedded software might effect:

  1. Use dynamic voltage and frequency scaling [DVFS] to tune the CPU performance to the needs of the moment.
  2. Disable [power down] currently unused peripheral circuitry.
  3. Make use of the CPUs low power modes.

In the conversation, my interlocutor seemed to latch on to (3), which caused me to start thinking about how these modes should be used … Read the rest of this entry »

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 emailRead the rest of this entry »

Some time ago, I recorded the content for a Web seminar about power management in embedded software. Although I am talking about the subject generally, I am, of course, strongly alluding to the capabilities incorporated into Nucleus RTOS.

The session was “broadcast” last week, but, if you would like to experience a rare example of me being caught on video, you can watch the recorded version. If you would like a copy of the slides or have any questions, please email.

This week I am on my annual pilgrimage to Nuremberg, Germany to attend Embedded World. This is the first major conference of the year that covers embedded software and is, I am sure, now the largest event serving this community anywhere in the world.

I have written about past visits and this year’s trip will be quite similar, except that I will be rather busy … Read the rest of this entry »

It is quite common, as I am sure it is for you, that someone asks me what I do for a living. Most of the time I try to get away with just saying that I work for a software company. If pressed for more detail, I end up explaining what embedded systems are all about. Sometimes, when really pushed, I talk about how I actually spend my time – writing articles, do webinars, presenting at conferences, etc. I have been known to call myself a “professional enthusiast”.

Last week the completion of a couple of my outbursts of enthusiasm … Read the rest of this entry »

I recently attended an event focused on power and embedded software hosted by the NMI in the UK, where I had been invited to make a presentation. My session was titled “Power Management in a Real Time Operating System”. If you would like a copy of the slides, please email.

Of course, apart from presenting myself, I was interested in the other sessions, in particular one about compilers and power consumption … Read the rest of this entry »
