NDP101

NDP101 Neural Decision Processor™

The Syntiant  NDP architecture is built from the ground up to run deep learning algorithms.  The NDP101 achieves breakthrough performance by highly coupled computation and memory, exploiting the vast inherent parallelism of deep learning and computing at only required numerical precision. The devices combine these elements to achieve approximately 100x efficiency improvement over stored program architectures such as CPUs and DSPs.

Ultra-Low-Power Consumption

Micro-watt level active power consumption, while always-on and listening

System-on-chip

Programmable general purpose IO, SPI Master and ability to boot from a serial flash enabling the NDP100 to be the only processor in the system

Neural Processing

Neural network with over half a million parameters providing large scale parallelism for sensor-based applications

Keyword Speech Interface

Created from the simultaneous classification of dozens of keywords

Ease of Use

Multiple, flexible methods to access neural processing engine where the user has full customization of applications and post-processing
