As the microprocessors embedded developers become more powerful and the software they design and write gets more complex and increases in size, they are faced with not just increasing opportunities, but also with the need to make the code as safe as is possible to use.
This is first being driven by such traditional application segments such as military-aerospace, automotive and medical, which all have strict software certification requirements testing standards in place. The second driver is the uncertain nature of the interactions between these segments with the totally......
Managing the growing confusion of opportunities described by the all encompassing use of the term "Internet of Things" requires clear thinking and categorisation, as well as fewer marketing managers tying their "things" to an inappropriate bandwagon.
The Internet of Things—indeed many aspects of electronics and embedded systems design—needs a standards group for naming things, much like the IETF, to define what things are and what they mean. And its membership should exclude vice presidents of marketing, product marketing manager......
As multi-core and manycore systems emerge whose complexity is daunting to embedded software developers, they have looked with envy at standardisation efforts such as IEEE's IP-XACT. This standard defines and describes electronic components for EDA hardware design.
Created initially by the SPIRIT consortium, IP-XACT defines and describes electronic components and their designs as a way to automate configuration and integration of the various EDA tools in an system on chip design.
This was done by creating a standardised XML data format to describe compone......
Like most of you I am surrounded by many "wonders" of the new world of connected computing, such as smartphones and variety of social networking environments. While they have their place, what fascinates and absorbs me about the Web and the Internet to a degree they can never do are the places that search engines can take me.
Maybe it is the knowledge glutton in me, but when I am on good search engine—such as Advanced Google, Google Scholar and the IEEE and ACM Digital Libraries – and have a topic that compels me to learn more, I'm in heaven.
Embedded system designers dwell largely in the digital domain, but the world is mostly analogue, so that means that to some degree they must be familiar with the methods and techniques for transforming that real world into a form they can manipulate in their designs.
In most cases that has meant having at least one member of a product development team who was an analogue design specialist or, alternatively for the digital designers to become more expert in designing in the analogue domain.
Some recent product introductions seem to me indicative of yet a new wave of tools a......
Looking at the range of recent news, product introductions, design and technical articles, it is hard to believe there was once a time when there was no PCI Express or any of its Peripheral Component Interconnect progenitors.
Shortly after the Intel x86 architecture exploded into the market place in the mid-1970s, all there was in the many homebrew personal computers and single board computers developed for industry was the S-100 bus, originally nothing more than the pins of the Intel 8080 run out onto the backplane to form the single system bus.
But after about five yea......
One of my favourite new books and one I frequently go back to is James Gleick's new opus titled "The Information". It is about information theory and Shannon's contributions, among others, to understanding its implications not only to engineering but to any aspect of research into the natural world.
While it is technically rough going sometimes, what brings me back again and again to reading it is that it is "the biography of an idea," as one reviewer said. While he does not spare the reader by dumbing down the complex technical issues, Gleick is abl......
For most of its existence (since the late 1990s), the H.264 video coder specification (aka MPEG 4, class 10) has been the video codec compression/decompression algorithm of choice in most consumer embedded and mobile devices. At last count, there are about 50 companies who supply the H.264 hardware/software building blocks necessary for building video-capable devices and systems.
A few years ago, that domination appeared to be threatened by Google's introduction of its open source WebM video coder it was recommending to hardware and software developers building And......
In a recent column, Jack Ganssle enthusiastically greets the arrival of Ada 2012 because it incorporates features and capabilities that he has been working hard to convince C and C++ embedded systems programmers to adopt explicitly and after the fact into their programming practices.
Even with the new capabilities incorporated into Ada 2012, there remain sceptics in the developer community who do not think Ada will be a factor in the mainstream of embedded programming. Part of that is due to the fact that Ada was developed in the early 1980s as a programming language for safety-......
Before the Internet began turning into a means of distributing mass entertainment and infotainment, there was once a clear delineation between two types of network operation.
One type included the real time and deterministic networks that served the specialised needs of industrial/ machine control and factory automation. The other included asynchronous networks in business and personal computing where the need was for reliable delivery and for which determinism and precisely timed delivery was a secondary consideration.
This is changing rapidly. Many of the......
