NDP200 Neural Decision Processor™

The Syntiant® NDP200™ is a special-purpose processor for deep learning and is ideal for always-on applications in battery-powered devices. The NDP200 applies neural processing to run multiple applications simultaneously with minimal battery power consumption. Built using the Syntiant Core 2™ programmable deep learning architecture, NDP200 is designed to natively run deep neural networks (DNN) on a variety of architectures, such as CNN, RNN, and fully connected networks, and it performs vision processing with highly accurate inference at under 1mW.  NDP200 brings a level of ML performance that delivers 25x the tensor throughput than the Syntiant Core 1™ found in the Syntiant NDP100™ that are currently shipping in high volume. A programmable Tensilica Hifi3 DSP Is also added for feature extraction and signal processing.
