NDP115 - Always-On Speech & Sensor-Fusion

The Syntiant® NDP115™ is a special purpose processor for deep learning and is ideal for always-on applications in battery-powered devices. The NDP115 applies neural processing to run multiple applications simultaneously with minimal power consumption.
Built using the Syntiant Core 2™ programmable deep learning architecture, the NDP115 is designed to natively run multiple deep neural networks on a variety of architectures, such as CNNs, RNNs and fully connected networks. NDP115 brings a level of ML performance that delivers 25x the tensor throughput than the Syntiant Core 1™ - found in the production Syntiant® NDP100™ - and is able to run speech inferences at a mere 280 microwatts. A programmable Tensilica® HiFi 3 DSP is included for flexible feature extraction and classical audio processing.
