FPGAs solve core IoT challenges
The Internet of Things (IoT) has become a wildly popular term these days, often used to describe a world in which virtually every electronic device connects to the Internet and each other. It comprises a staggering list of applications — everything from smart consumer appliances and vehicles to wearables — and that list will only grow as mobility continues to explode. But this growth brings with it implementation challenges to which solutions need to be found.

Smart, connected devices, and the IoT ecosystem they are helping to create, promise to transform everyday life. For individual consumers that might mean making devices more efficient and cost effective for their daily tasks, keeping them safer, or even helping ensure they live healthier lives. For businesses, the IoT promises significant advantages in terms of automation, energy efficiency, asset tracking and inventory control, shipping and location, security, individual tracking, and energy conservation.

But to reach the tens of billions of devices projected to make up the IoT, designers will have to overcome significant implementation challenges. Some of the key among them will be making IoT devices power efficient, handling incompatible interfaces, and providing a processing growth path to handle the inevitable increase in device performance requirements. An FPGA-based design approach can help address such challenges.


Challenge 1 – Power Efficiency

The IoT is a powerful concept with capabilities promising to literally transform the way society lives and works. In fact, development is currently underway in a variety of areas that will make many things look very different than they are today—and not just from a consumer perspective.

Consider, for example, that wearable devices like the Nike FuelBand often require eight or nine components such as the processor, the wireless module, memory, a display, eight sensors, and a USB interface. Over the next few years, component counts may drop, but the complexity and transistor count of the three or four remaining components will grow rapidly as more memory and processing power is required, and as screen resolutions and brightness increase.

Achieving an energy efficiency that will enable IoT devices to run for years on a single battery will not be an easy task. It demands the use of low-power components and more efficient power systems. And, it will require changes at both the architectural and silicon level.
