NDP115
Neural Decision Processor
Always-on Speech & Sensor-Fusion Processor
The Syntiant® NDP115 Neural Decision Processor™ is a special purpose chip deep learning and is ideal for always-on applications in battery powered devices and other power constrained systems. The NDP115 applies neural processing to run multiple applications simultaneously with minimal power consumption. Built using the Syntiant Core 2™ programmable deep learning architecture, NDP115 is designed to natively run multiple Deep Neural Networks (DNN) on a variety of architectures, such as CNN, RNN and fully connected networks. NDP115 brings a level of ML performance that delivers 25x the tensor throughput compared to the Syntiant Core 1™ embedded in Syntiant’s NDP100 and NDP101 devices, and is able to run speech inferences at a mere 280 microwatts. A programmable HiFi 3 DSP is available for flexible feature extraction classical audio processing.
The NDP115 supports dozens of application-defined audio sequences for a variety of use cases including:
| Far-field, near-field and close-talk voice interface
| Multiple wake words and local commands
| Acoustic Echo Cancellation (AEC), noise suppression, beamforming
| Speech enhancement
| Speaker identification and verification
| Acoustic event and scene classification
| Multi-sensor fusion
