FACT SHEET
eIQ™ ML SOFTWARE
OVERVIEW
The NXP
environment provides the key ingredients to do inference
with neural network (NN) models on embedded systems
and deploy ML algorithms on NXP microprocessors and
microcontrollers for edge nodes. It includes inference
engines, NN compilers, libraries, and hardware abstraction
layers that support Google TensorFlow Lite, Glow, Arm
NN, Arm CMSIS-NN, and OpenCV.
With NXP’s i.MX applications processors and i.MX RT
crossover processors based on Arm Cortex
respectively, embedded designs can now support deep
learning applications that require high-performance data
analytics and fast inferencing.
eIQ software includes a variety of application examples that
demonstrate how to integrate neural networks into voice,
vision and sensor applications. The developer can choose
whether to deploy their ML applications on Arm Cortex A,
Cortex M, and GPUs, or for high-end acceleration on the
neural processing unit of the i.MX 8M Plus.
APPLICATIONS
eIQ ML software helps enable a variety of vision and sensor
applications working in conjunction with a collection of
device drivers and functions for cameras, microphones and
a wide range of environmental sensor types.

OPEN-SOURCE INFERENCE ENGINES
The following inference engines are included as part of the
eIQ ML software development kit and serve as options for
deploying trained NN models.
Arm NN INFERENCE ENGINE
eIQ ML software supports Arm NN SDK on the i.MX 8 series
applications processor family and is available through the
NXP Yocto Linux-based releases.
Arm NN SDK is open-source, inference engine software that
allows embedded processors to run trained deep learning
models. This tool utilizes the Arm Compute Library to
optimize neural network operations running on Cortex-A
cores (using Neon acceleration). NXP has also integrated
Arm NN with proprietary drivers to support the i.MX GPUs
and i.MX 8M Plus NPU.

Neural Network (NN) Frameworks
GLOW
eIQ ML software supports Glow neural network compiler
on the i.MX RT crossover MCU family and is available in the
MCUXpresso SDK.
Glow is a machine learning compiler that enables aheadof-time compilation for increased performance and smaller
memory footprint as compared to a traditional runtime
inference engine. NXP offers optimizations for its i.MX RT
crossover MCUs based on Cortex-M cores and Cadence
