i.MX106A AUDIO CROSSOVER
PROCESSOR OVERVIEW
The i.MX RT106A is a solution-specific
member of the i.MX RT1060 family of
crossover processors, targeting cloud-
based embedded voice applications. It
features NXP’s advanced implementation
of the Arm
®
Cortex
®
-M7 core, which
operates at speeds up to 600 MHz to
provide high CPU performance and best
real-time response. i.MX RT106A-based
solution enables system designers to
easily and inexpensively add voice control
capabilities to a wide variety of smart
appliances, smart home, smart retail, and
smart industry devices. The i.MX RT106A
processor is licensed to run NXP’s turnkey
voice assistant software solutions, which
may include:
` Far-field audio front end softDSP
` Acoustic echo cancellation
` Ambient noise reduction
` Beamforming
` Barge-in
` Playback processing
` Codecs
` Wake word inference engine
` Media player/streamer
` MQTT, lwIP, TLS
` Discovery and onboarding
` All drivers, including Wi-Fi
®
and
Bluetooth
` Supported by MCUXpresso SDK,
IDE and Config Tools
