This reference kit is designed for commercial developers bringing an Alexa built-in experience to consumer electronics, smart home devices, and industrial applications. NXP’s i.MX 8M Development Kit for Amazon AVS introduces a number of ‘firsts’ in a dev kit by a semiconductor company: pre-integrated Alexa Multi-Room Music (MRM) capabilities, far-field voice capture with only two microphones, and inclusion of the Amazon Wake Word Engine.
The dev kit’s i.MX 8M quad core A53 and M4 architecture offers advanced processing and low-power operation capabilities. The single chip solution for AVS is based on the Pico i.MX 8M development board with an auxiliary 2-microphone array board and delivers far-field quality voice detection performance in a compact package. To enable a high-quality audio experience on the i.MX 8M, NXP leverages DSP Concepts for audio processing and noise suppression algorithms including beamforming and stereo acoustic echo cancellation.
