CEVA, Inc. has added Bluetooth support to its TeakLite-4 DSP IP core, making it available to developers of a wide range of Internet of Things applications on smartphones,, wearables and wireless audio devices.
Leveraging new instructions and interfaces added to the recently introduced multifunctional CEVA-TeakLite-4 v2 architecture, the DSP now runs CEVA-Bluetooth connectivity (Classic or Low Energy). In addition it supports a broad range of audio and voice software packages, 'always-on' user interface (UI) functions such as voice triggering and face activation, as well as a full suite of sensor-fusion capabilities.
According to Eran Briman, vice president of marketing at CEVA, the Internet of Things comprises a multitude of devices, technologies and form factors, with many use cases and requirements.
He said CEVA-TeakLite-4 specifically targets user-centric IoT devices, where natural user interface, audio playback and voice communication represent key attributes of the device.
“This can include for example, voice activation, face triggering and other 'always-on' functionality in a smartphone, smart watch, smart home controller or wireless speakers,” said Briman adding that the ultra-low power nature of the CEVA-TeakLite-4 DSP ensures that these 'always-on' features consume minimal battery life.
Implementing the Bluetooth Low Energy, always-on UI and sensor fusion on the CEVA-TeakLite-4 DSP requires less than 150K gates and consumes less than 150uW when implemented in a 28nm process.
