CEVA Sextuples Speed of SensPro Smart Devices Sensor Hub

Smart sensor technology developer CEVA has upgraded its SensPro sensor hub to process data up to six times faster overall and 10 times faster when it comes to audio AI processing. The multisensory system acts as a central depot for visual, audio, and other data. The new generation marks a big step up in performance, less than a year after the first generation of SensPro came out.

Sensing More

SensPro2 adds and expands to the existing power of the sensory hub, where environmental information is collected and analyzed. The AI built into the system uses context to organize the incoming data and can be trained over time to understand more about how the information it receives fits together. A home security system using SensPro2 could, for instance, use a camera to see a car going by and mark its color, model, and license plate, while microphones pick up its engine sound before it arrives, and a radar sensor could work out how fast it is going. If it’s a car that regularly speeds through a residential neighborhood, it could collate all of that information and alert the user ahead of the car’s arrival to make sure they are not in danger of being in the road and in danger. The system as a whole is quite flexible, with application-specific instruction set architectures (ISAs) for the various potential sensors.

“Our new SensPro2 family of power-efficient sensor hub DSPs offers scalable performance, multiple precisions and high utilization for the increasingly complex and diverse AI/sensor workloads of contextually-aware devices,” CEVA vice president of research and development Ran Snir said. “The SensPro2 architecture is unique and innovative and uses a common ISA enabling seamless software reusability across all the SensPro2 DSPs. Our customers highly value this, along with the application-specific ISAs, as they increasingly utilize SensPro2 cores in their product designs.”

Sensory Soaring

SensPro2 speeds up the system’s processing, recognizing information, and placing it into the relevant context far more rapidly. In verticals like home voice assistants, healthcare, and automobiles, that speed can make all the difference. The upgraded software includes several other improvements on the first SensPro, including double the memory bandwidth while operating more efficiently and using less power. The sensory hub’s improved architecture continues to take advantage of CEVA’s many smart sensory software products, such as the WhisPro speech recognition and ClearVox noise reduction services. The upgrades will also likely boost CEVA’s prospects as a partner for smart devices, whether in the car or home. CEVA previously has partnered with Novatek Microelectronics last year to bring its audio tech to Novatek’s smart TV hardware and with audio software developer Bragi to set up a hearables platform, combining the CEVA-BX software with Bragi’s operating system. With the new SP100 software accelerating audio data processing, CEVA can bring a lot more power to the table when working with Bragi and other partners.
