NDP120

Neural Decision Processor

Always-on Speech & Sensor-Fusion Processor

Product Brief • Data Sheet • Press Release

The Syntiant® NDP120 Neural Decision Processor™ is a special purpose chip for audio and sensor processing for always-on applications in battery powered devices and other power constrained systems. 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 CNN, RNN and fully connected networks. NDP120 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. A programmable HiFi 3 DSP is available for classical audio processing.

The NDP120 supports dozens of application-defined audio sequences for a variety of use cases including:
