Featuring speech inference at 280 Watts, NDP115 is looking to make a home in wearables and smart appliances.

Syntiant NDP115 Neural Decision Processor

Syntiant’s NDP115 Neural Decision Processor™, the latest addition to the company’s family of special-purpose silicon, was unveiled on Jan 4 by Syntiant Corp., a deep learning solutions provider for edge AI applications. It was built using the company’s Syntiant Core 2™ inference engine, which can run multiple neural network loads at less than 1mW.

Despite being small, the NDP115 can deliver highly accurate, cloud-free audio and sensor AI processing for a broad range of edge products, from smart homes, like remote controls, to consumer electronics, such as hearables and wearables, to industrial solutions for predictive maintenance. It is available in a 2.1 mm x 2.1 mm 25-ball WLBGA package (0.4 mm ball pitch). 

CEO of Syntiant, Kurt Busch, said, “ The NDP115 offers the multi-modal functionality of our Core 2 inference engine in a compact, cost- and power-efficient solution for ultra-power and size-constrained applications.” Furthermore, he added, “combined with our machine learning software models, the purpose-built NDP115 enables developers to easily deploy full audio and sensor processing solutions that address all kinds of consumer and commercial use cases, from home security to industrial IoT.

The NDP115 is built to natively operate several deep neural networks on various architectures, including CNNs, RNNs, and fully connected networks, and is capable of making speech inferences at 280 microwatts. Sensor fusion, tilt, magnetic field, and pressure are all supported by the NDP115 via I2C and pulse density modulation (PDM). It is ideal for close-talk, far-field, keyword speech, and audio event classification applications.
