Software Development Tools

SW Dev Tools
Syntiant provides software development tools to help evaluate the Neural Decision Processors. 

Training Development Kit (TDK):

The TDK provides materials and instructions to train neural networks to target the Syntiant NDP devices. The TDK also includes examples to train several demonstration-grade models out of the box.  The TDK includes:

▪ Step by step instructions for server configuration

▪ An accurate model of the essential hardware details of NDP devices integrable into a production training pipeline enabling creation of high-performance audio and speech recognition models

▪ The Syntiant Packager tool to extract a model parameters (weights and biases) from the deep learning framework to a binary file that can be on the NDP with Syntiant NDP device control SDK APIs

▪ An MNIST handwriting recognition example

▪ A speech recogntition sample

Software Development Kit (SDK):

The SDK contains the tools and software required to control and operate Syntiant NDP devices.  The SDK includes:

▪ NDP device control interface library (ilib) source code

▪ NDP Linux driver source code

▪ A Python ilib wrapper

▪ A Python-based development and diagnostic command line interface application

▪ C-based minimal example applications

▪ Compiled binaries for Raspberry Pi 3B+

▪ A high-performance Alexa wake word neural network model

▪ Additional demonstration-grade speech and MNIST digit recognition neural network models
