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.

Linux and the first-time developer’s journey

Any electronic design engineer practicing today will be familiar with open source software. Nowadays, it is likely that the question of using an open source operating system is always on the agenda at a new project kick-off meeting.

RAM scoops up computation

It may be nothing more than a short-lived fad. But the rapid ascendance of machine learning in computing since deep learning became practical has pushed hardware development in a new direction that could have a major effect on how computer designers think about memory.

Discrete DRAM components v modules

A common practice when designing embedded computing systems for aerospace and defence applications is to use down-board DRAMs which are extremely reliable, have very efficient thermal ratings and the fastest electrical characteristics.

Gone in a flash

Device form factors come and go. Here, Michael Barrett looks at removable memory and warns of the importance of considering how long its form factor will be around.

A testing challenge

The challenges associated with the development of autonomous vehicles are immense but, perhaps, testing is the biggest one.

Making connections

PCB Design and Manufacturing Live opens its doors for a second year, welcoming a host of the industry’s PCB experts.

Breaking up is hard to do

In mid-March, graphics processor maker NVIDIA decided to outbid Intel by close to a reported $1bn in the pursuit of networking chipmaker Mellanox. For the NVIDIA of several years ago, it would have been an acquisition that made little sense, but today it is no longer serving just framerate-hungry players of Call of Duty.

When development never sleeps

Is software ever finished? As Leonardo da Vinci observed with art 500 years ago, it is not so much finished as worked on until it is time for it to be abandoned.

Loose threads

Timing can be tricky in embedded systems. Shortly after it touched down on the surface of Mars in 1997, NASA’s Pathfinder lander started to malfunction, triggering a watchdog timer that engineers tried to fix with system resets.

On-going battle

The aerospace and defence sector is flourishing, bring with it rising profits and new possibilities in terms of travel, exploration and defence.
