Embedded

Software dominates the embedded system design process; according to some estimates, software development can now consume up to 70% of a project’s resources.

Traditionally, software development started when the hardware arrived, but not any more: software designers are using virtual prototypes to get their projects started in time to meet the deadlines.

But there are also operating systems, which manage this growing complexity. The choices are numerous and have an impact at the system level, as well for deeply embedded products. And C is no longer the only programming language.

Whatever the complexity of the embedded system you’re developing software for, New Electronics addresses the issues regularly by looking at the latest tools and techniques available.

Extensions to FreeRTOS bring productivity gains to embedded design engineers

Operating systems can be a major source of stress for embedded design engineers. Factors such as size, cost and support all contribute to make the development process more complex. The process can become even more fraught when engineers look to develop products with real time operating systems. An off the shelf operating system can play an important role in keeping costs and development time as low as possible.

Is the hardware engineer becoming an ‘endangered species’?

There is general agreement that software is now the dominant part of the embedded design process. There is also a trend towards platform based design, with variants created by software differentiation, and the use of SoCs and ASSPs as 'black boxes'. So is hardware design becoming less relevant? Is the hardware designer an 'endangered species'? Time to turn to the experts.

How in the loop testing aids embedded system validation

Embedded systems software can provide competitive advantage. For a vehicle, software can make a comfortable ride even more appealing; it can also reduce cabin noise or fuel consumption. Some of this functionality could, potentially, be implemented in hardware, but that would increase manufacturing cost and product price. Software also enables reuse and can be updated more frequently to satisfy user needs.

Beat the clock: System design and frequency management

Clocks are the 'heart beat' of almost all electronic systems and clock management is an especially important part of the overall system design. Since clock accuracy, stability and overall signal quality affect system performance, choosing the right timing solution that fits the design application is critical.

Developing rugged robots for the nuclear industry

Robots have fascinated humans for many years and the idea of having a remotely controlled or autonomous machine at our beck and call has always appealed. But robots are becoming increasingly important in areas where humans cannot go – from war zones to hazardous industrial environments. The Japanese have even developed a robot to collect injured people in areas that medical crews cannot reach.

Model behaviour: Autosar

Autosar is a major topic when it comes to discussions about automotive design. While much has been written about the architecture, the benefits of reuse, exchangeability and redistribution of functions, what does Autosar mean for those who actually develop a car's functionality?

Top 10 considerations when choosing memory

Nexus GB, the exclusive UK distributor of Datakey Electronics' range of rugged portable memory products, has produced a checklist of issues that OEMs should consider before integrating portable memory into a new design.

Setting your priorities

The increasing complexity of today's microcontroller systems is making ever greater demands on the embedded software engineers that bring them to life. At the same time, the latest microcontrollers are achieving higher performance than ever, with more complex peripherals and larger embedded memories.
