Anil Khanna Citius, Altius, Fortius Faster, Higher, Stronger – the Olympic motto could just as easily be applied to the expectations driving the alarming rate of evolution of embedded hardware. In the form of today’s mobile devices, we now hold more processing power than high-end PCs of yesteryears! A single mobile device has replaced the functionality of a myriad of discrete devices: GPS, camera, pager, voice … Read More

Anil Khanna This is part 2 of a current blog. Opening the source, I was quickly able to locate the code responsible for animation: Because of a 100% CPU cost, I was expecting to find something clumsy, but found the code to be reasonable. It is using Qt's built-in Property Animation framework. A quick Google search showed that it is the standard way of implementing animation in Qt. This is how Qt's own examples … Read More

Anil Khanna Occasionally, I get a chance to introduce our engineers, and showcase their work, through this blog. This time, it is the turn of Asad Zia, our resident expert on all things graphics and UI related. Asad and I have worked on a few projects before, notably this whitepaper on Debugging Graphics Synchronization issues with Sourcery Analyzer. I recently had a chance to collaborate with Asad again as he … Read More

Colin Walls After talking about low power CPU modes last week, I make no apology for returning to the topic. Reducing power on a single core embedded system is a challenge. With a multicore design, there are many other nuances. As with most system development, there are two highly interrelated facets to the process: design and verification [which software developers commonly call debugging]. Different semiconductor … Read More

Ricardo Anguiano Andrew Stubbs, an esteemed member of our Embedded Software Tools team, recently got a chance to show off his debugging and performance tuning skills on an innovative multi-process, multi-language, network distributed application. Andrew built a three element client-server software build system enhancement called cs that provides a build performance boosting cache feature while capturing usage data … Read More

Ricardo Anguiano Software development on early stage custom hardware platforms is not for mere mortals. The hardware isn’t finished yet, so the software team must wait for prototype boards to arrive. Then there’s the build, flash, test and debug cycle. Traditional, JTAG and printf-style debugging are hard enough but when application performance must be improved, there’s when the real wizardry takes … Read More

Colin Walls Last week there was a new release of Sourcery CodeBench, which I saw somewhere posted as “A Christmas present from Mentor Embedded”. As this release covers a wide range of functionality in both Sourcery CodeBench and Sourcery Analyzer, I thought it would be interesting to focus on a specific new feature and dig into the technology a little. I have been investigating Diagnostic Log and Trace … Read More

Hollis Blanchard Ever had to work closely with someone else to debug a problem? Maybe there’s a nasty bug that Alice can’t reproduce, but Bob seems to hit it every time. In large software projects, Alice and Bob might not even work for the same company: one company doing integration reports problems with a component that another company built… but problems that are only visible in the integrated system. In … Read More

Ricardo Anguiano Imagine this scenario: Your custom hardware design is still being worked out by your hardware team. Early stage, pre-silicon design models are running in simulation. The software team has started their work using this hardware simulation and they’ve got Linux running on the simulated target and they are now debugging kernel, driver and application code. The software team helps exercise the … Read More

Colin Walls Last week, I talked about self-testing possibilities for embedded software, where the goal was to detect and mitigate the effects of hardware failure. I commented that further work could be done to address the issue of software failure and this would need to wait until a future occasion. That time has come … All non-trivial software has bugs. Obviously, well designed software is likely to have … 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

Colin Walls Developing embedded software used to be easy. Actually, that is not true. It has never been easy, but certain matters were simpler. Embedded developers have always needed more control of code generation because, as I am often heard to chant, every embedded system is different and the priorities and requirements change from one to another. It used to be broadly a choice between speed and size of code, … 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

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
