Syntiant Always-On
Speech & Sensor-Fusion Processor
NDP120


NDP120 Neural Decision Processor™
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.
Neural Processing
Second generation Syntiant Core 2 supports energy efficient inference and delivers 25x the tensor throughput compared to NDP100/101
Ease of Use
Flexible methods to access neural processing engine where neural designers have full control of network configurations
Multi-sensor fusion

PDM, SPI, I2S and I2C interfaces for microphone and sensor applications
Multi-feature
Concurrent neural networks to run multiple applications simultaneously with minimal power consumption
Audio Processing
DNN + DSP support both machine learning and traditional audio and voice algorithms
Applications
The NDP120 brings audio and multi-sensor processing for always-on applications in battery powered devices. Longer battery life and higher performance can be achieved with NDP while the primary processor is asleep.
