Neural Decision Processors 

NDP120 - Always-On Speech & Sensor-Fusion

The Syntiant® NDP120™ is a special purpose processor for deep learning and is ideal for always-on applications in battery-powered devices. The NDP120 applies neural processing to run multiple applications simultaneously with minimal power consumption.

Built using the Syntiant Core 2™ programmable deep learning architecture, NDP120 is designed to natively run multiple Deep Neural Networks (DNN) on a variety of architectures, such as CNNs, RNNs and fully connected networks.  NDP120 brings a level of ML performance that delivers 25x the tensor throughput than the Syntiant Core 1™ found in the production Syntiant® NDP100™. A programmable Tensilica® HiFi 3 DSP is included for flexible feature extraction and classical audio processing.
