Colin Walls On desktop computers, data that you are working on right now, in an open application, is most likely just stored in RAM. When you are finished, the information is saved to disk for more permanent storage. That is the way it is for word processing, spreadsheets etc.; databases are bit different. The idea of having volatile memory for temporary use – where a power failure can cost you a morning’s … Read More

Smart Energy panel

Posted by Colin Walls

Colin Walls Smart Energy is a topic that I have discussed here a bit – here and here for example. It is a somewhat vague term that encompasses home automation, networking of appliances in the home and online connectivity to utility companies. These are all areas that will see significant growth in the coming few years. On Wednesday this week, I will be chairing an online Smart Energy panel session. This is … Read More

Anil Khanna The smart energy market and the adoption of “smart” products continue to evolve at a rapid pace. While several factors, such as cost, environmental concerns, local policies etc. impact the rate of acceptance of smart energy, technology is playing a key role in fostering it. The advantage is that there is a growth in applications both at the larger networked grid-level as well as (and more so)at the … Read More

Colin Walls A topic, that seems to interest many embedded developers, is the performance of an RTOS and how that might be measured. It is certainly a subject which is well received at conferences, where numerous questions are commonly posed. Broadly speaking, I would rather discourage developers from getting too hung up on the performance figures published by RTOS vendors, as it is incredibly difficult to use them … Read More

Ricardo Anguiano Stella, our Nucleus powered, self-balancing robot generates kernel and application level trace data which is then visualized using Sourcery Analyzer. Arvind Raghuraman, Staff Engineer on the Nucleus RTOS team and creator of Stella, will give you a tour of Stella’s application layer trace visualization. Arvind previously instrumented Stella’s relevant application layer variables including … Read More

Ricardo Anguiano Stella, our Nucleus RTOS powered, self-balancing robot generates kernel and application level trace data which is then visualized using Sourcery Analyzer. Sourcery Analyzer is used to detect and explore wheel angle bias, and test the hypothesis that perhaps the corrective pulse width signals are causing the wheel angle bias. We also use the measurement tool to quantitatively characterize the worsening … Read More

Phil Burr How many times have you tried prodding at the screen of a device and only after it has failed to respond have you remembered that it isn’t actually a touch screen? I know that I have done this, and after talking to a friend of mine who is a doctor in my local hospital, I am pleased to know that I am not the only one! It is no surprise that the medical profession’s expectations of user interfaces has … Read More

Munich conferences

Posted by Colin Walls

Colin Walls I attend quite a few conferences, taking any opportunity to speak about embedded software matters. Although such events take place throughout the year, there are two notable periods: Summer [July/August], when everything goes very quiet, and early Fall [late September and October], when everything goes mad. We are just beginning the “quiet” period. But there were a couple of events scheduled … Read More

Colin Walls Answering questions is something that I am often expected to do. Maybe I am presenting at a conference, doing an online seminar, hanging out on a trade show booth, writing blogs or articles – these all elicit questions. Sometimes I am asked by a salesperson to respond to a customer’s question. I would always do my best to give a complete and accurate answer and certainly aim to be truthful. … Read More

Nucleus, Sourcery Analyzer

26 Jun, 2013

Ricardo Anguiano So, what sorts of things can you create with Mentor Graphics’ embedded software development tools and platforms?  How about a self-balancing robot named Stella?  The Nucleus ReadyStart development platform, which includes the Nucleus RTOS, Sourcery CodeBench IDE and toolchain and Sourcery Analyzer performance and analysis tool, was used in the development of Stella. Stella the robot is an inherently … Read More

SEP 2.0

Posted by Colin Walls

Colin Walls When I first heard the term “Smart Energy”, I confess that I had no idea what it meant. For a while, a precise definition seemed to elude me, as people would talk about smart meters and the Smart Grid, but not actually say what smart energy was. It is now a little clearer. Smart Energy is really a catch-all term for a bunch of technology associated with energy efficiency primarily in a domestic … Read More

Colin Walls One of the great things about software, compared with hardware, is the ease with which it may be changed and updated. The big downside of software is also the ease with which it can be changed. This ease can make software developers lazy, as they know that they can always fix things later. This is a sharp contrast to chip developers who are fearful of errors, as an ASIC respin is both time consuming … Read More

Using an SMTP client

Posted by Colin Walls

Colin Walls I always find it satisfying to see simple solutions to apparently complex problems and the world of embedded software certainly lends itself to some creativity. My concept of “simple” is quite broad, but essentially encompasses anything that is easy to understand [for me] and ideally avoids reinvention of any wheels. A while ago, I wrote about incorporating a Web server [HTTP server actually] … Read More

Anil Khanna Nucleus, our flagship RTOS offering has been around for several years now. In this time, it has been designed into more than 3 billion embedded devices in various applications such as mobile, medical, consumer electronics, industrial and more! The phrase “been there done that” could not be more appropriate to Nucleus. Regardless, when it came time to design yet another cool demo, our engineers were … Read More

What is an FPGA?

Posted by Colin Walls

Colin Walls In the early days of embedded systems, software engineers typically had some understanding of hardware design. Indeed, in many cases, it was the hardware designer who implemented the software. Over the years, as the amount of software development has increased, engineers have become less and less “hardware aware”. I find this transition interesting from the viewpoint of an embedded software … Read More
