UK semiconductor player Imagination Technologies has introduced a new energy-efficient radio processing unit (RPU) aimed at spurring the development of new Internet of Things (IoT) devices in a range of areas, including mobile health, energy and agriculture.

Imagination (Kings Langley, UK) says the new RPU – branded Whisper and forming an addition to the company’s existing Ensigma range of products – is designed chiefly for connected devices where ultra-low power consumption and low cost points are critical.

“Many devices claiming to address IoT today are in fact repurposed from other markets such as mobile or embedded, but don't fully address the extreme low power and cost requirements that this market will demand,” said Tony King-Smith, the executive vice president of marketing for Imagination. “With new Ensigma ‘Whisper’ RPUs, customers can create a whole new generation of life-enhancing and efficiency-focused devices targeting markets as diverse as eHealth, energy, agriculture, security and many other areas.”

Imagination claims that Whisper is suitable for a broad range of lower bitrate connectivity standards needed in IoT and other small-footprint connected devices.

In particular, the Whisper RPUs include hardware that improves the efficiency of power consumption.

Imagination also says the Whisper design builds on the success of its previously launched Ensigma RPUs, which are currently being used in a number of low-power audio and connectivity devices.

The company plans to roll out a line of Ensigma Whisper cores starting the fourth quarter of the year.
