Google hangout on IoT

Posted by Colin Walls

Colin Walls The Internet of Things is a big issue right now, which I wrote about a few months back. Tomorrow I am moderating a Google hangout titled "Internet of Things (IoT) Connectivity for Embedded Devices" where some experts will discussing this important matter. You can register here and will have the chance to pose questions online. If you cannot attend, a recording of the session will be available afterwards. … 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 Apart from writing about embedded software matters, I also read widely and enjoy the perspectives offered by many of the key figures in the field. One writer, who always gets my attention, is Jim Turley. Jim is never afraid of raising contentious issues and tends to take something of a chip-centric view of embedded systems. He seemed surprised, in a recent article, to find that engineers’ priorities … Read More

Colin Walls Complexity never, in itself, impresses me. I am impressed people’s ability to understand complex ideas and create complex machines, but a truly elegant and simple solution is always what gives me most pleasure. This might beg the question as to why I work in software – a business well known for creating incredibly complex things. I often ask myself the same question. Systems where there … 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

Low power modes

Posted by Colin Walls

Colin Walls 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: Use dynamic voltage and frequency scaling [DVFS] to tune the CPU performance to the needs of the … Read More

Anil Khanna It is no secret that demand for electricity far outstrips available supply. Demand from both the rapid urbanization of developing economies as well as emergence of new applications in developed nations is driving this trend. Generating additional capacity is one, albeit quite expensive, option to deal with this imbalance. Alternatively, turning to technology to help address this issue is another. Source: … Read More

Jamie Little This is not your daddy’s 18-wheeler! We’re all quite familiar 18-wheeler diesel trucks. We see them on the road every day. They are a critical part of our mass infrastructure in various capacities. From moving companies, freight liners, to independent truckers, to retailers and package delivery, there are lots of big trucks on the road – collectively consuming significant amounts of diesel fuel. … Read More

Kamran Shah There are a number of heterogeneous multicore SoCs being introduced including the Vybrid platform from Freescale and the Jacinto 6 platform from Texas Instruments. At CES in January 2014 we demonstrated how the communication between Cortex M4 and Cortex A15 cores on the TI Jacinto 6 can be implemented using rpmsg. The two videos below show this demonstration in action. The first video illustrates how … Read More
