[OpenNAS] - Getting started Tutorial

OpenNAS is an open source VHDL-based Neuromorphic Auditory Sensor (NAS) code generator capable of automatically generating the necessary files to create a VHDL project for FPGA. OpenNAS guides designers with a friendly interface and allows NAS specification using a five-steps wizard for later code generation. It includes several audio input interfaces (AC&audio codec, I2S ADC and PDM microphones), different processing architectures (cascade and parallel), and a set of neuromorphic output interfaces (parallel AER, Spinnaker). After NAS generation, designers have everything prepared for building and synthesizing the VHDL project for a target FPGA using manufacturer&tools.
