Power management webinar

Posted by Colin Walls

Colin Walls 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. … Read More

Embedded World 2013

Posted by Colin Walls

Colin Walls 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 … Most years I have had one … Read More

Embedded World, Low Power, Power Management, RTOS

24 Feb, 2013

Kamran Shah The Mentor Embedded team will be at Embedded World in Nuremburg Germany this week. In addition to a number of demos at the Expo (Hall 5, Booth 324) we are presenting a number of sessions as well. On Tuesday Colin Walls will give two presentations: His first session is titled “Power Management in Embedded Systems”. This is part of Session 4: System Level Design and will be from 3:15 pm to … Read More

More on low power CPU design

Posted by Colin Walls

Colin Walls I recently wrote a posting about designing a CPU for low power by creating an instruction set where common sequences of instructions would have the minimum number of logic transitions. I hoped that I would get some feedback and I did. I had an email from Apostolos Leventis. I am always delighted to be contacted by blog readers, either by comment or email – even if it is critical or correcting … Read More

Designing a low power CPU

Posted by Colin Walls

Colin Walls First up, please remember that I am a software guy, not a chip designer. Please read this posting with that in mind. I was chatting with someone at a conference recently and they planted an idea in my brain. I am not sure what to do with the idea, so I thought that I would exercise it here. The topic was the consideration of power consumption in embedded systems – a subject I have written about … Read More

In the news

Posted by Colin Walls

Colin Walls 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, … Read More

IP-SoC, Low Power, Power Management

Kamran Shah

Collin Walls gave a recent keynote at the IP-SOC 2012 Conference titled “Power is now a Software Issue”. The keynote provides a nice overview of software considerations including hardware selection, use cases, the role of the operating system, BSPs and drivers as well as application development.

Power and compilers at the NMI

Posted by Colin Walls

Colin Walls 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 … Read More

ESC Boston

Posted by Colin Walls

Colin Walls This week I am making a flying visit to DESIGN East [a.k.a. ESC Boston] to present a couple of classes. When I say “flying”, I am not alluding to my mode of transportation, but the duration of my visit. My first paper is Wednesday afternoon and my second is lunchtime on Thursday; I fly in Wednesday morning and out again Thursday evening. I even manage to pack in some other activity while … Read More

The Power Pyramid

Posted by Colin Walls

Colin Walls Power consumption of embedded systems is currently a hot topic – one I have posted on several times before. With the conference season coming up, I am working on a few papers that address this subject and I will talk about those nearer the time. However, there is one aspect of designing for low power that I thought it would be worthwhile putting under the spotlight. I want to introduce the “Power … Read More

Going to sleep

Posted by Colin Walls

Colin Walls Once again, I am thinking about embedded software and low power design, as I have discussed before. I still find it interesting that a characteristic of electronic devices, which until only recently would have been considered purely a hardware issue, is now very much on the agenda for software developers. The challenge now is to keep up with the capabilities provided by the chip makers … There … Read More

A more powerful phone

Posted by Colin Walls

Colin Walls The subject of power in embedded systems just does not seem to go away – like my postings here and here. And I do not see the situation changing any time soon. If it is not design consideration for your current project, I promise that it will be on your agenda before long. As smart phones become increasingly ubiquitous, it seems worthwhile considering how concerns about power have influenced their … Read More

Power Suckers

Posted by Colin Walls

Colin Walls I have often observed that the world of embedded software is usually dominated by a small number of “fashionable” topics – technology that everybody is talking and/or concerned about. The key one just now, which I have discussed before, is the influence that software has on device power consumption. This is a topic to which I will certainly return. A number of the Mentor Embedded team … Read More

Freescale Technology Forum

Posted by Colin Walls

Colin Walls Nowadays, there is a perception that the higher end embedded CPU is dominated by ARM. Obviously, these devices are very popular, as evidenced by the various ARM Tech Con events around the world. However, I remember the world before ARM, when “embedded 32-bit device” meant Motorola 68000 family. Motorola Semiconductor became Freescale, who are still a force to be reckoned with. Freescale’s … Read More

Welcome to my little corner of the world

Posted by Chris Hallinan

Chris Hallinan I always start the New Year thinking I should get in shape and lose a few pounds (That’s lbs not £ - I’d very much like to gain some £’s). The last couple of years the whole family has signed up for a local fun run that takes place in March. This creates that classic compelling event that means we have to get off the sofa and do a bit of training. Last year I was pleased that I managed to keep … Read More
