Tensilica Xtensa Neural Network Compiler v2

Length : 1/2 day

Course Description

This course introduces the Xtensa Neural Network Compiler (XNNC) v2.

The purpose of the Xtensa® Neural Network Compiler (XNNC) is to convert a floating-point Convolutional Neural Network (CNN) into an optimized, fixed-point solution for Cadence Tensilica® processors. The course aims to guide the user to the effective use of configuring and running supported neural network models through the different stages and modes of the XNNC workflow. This includes how to configure inputs and outputs for a network and the usage of the Custom Operator Application Interface (API).  

The course describes the added support for Graph Lowering (Glow) Compiler techniques, Tensorflow convertors, Open Neural Network eXchange (ONNX), and Caffe2. The course also explains the use of new Quantization schemes and Xtensa Exchange Formats for generated DSP codes.
