Tackling the complexities of edge-connected, machine learning (ML)
applications can be a daunting and long process. Combining the functions of an
involved application with the intricacies of deploying that ML model on a
cost- and power-effective platform requires significant effort and time. NXP’s
ML-based system state monitor application software pack (App SW Pack) provides
product-ready source code for rapid development of such a complex application.
Building edge-ready solutions is not an easy process, and today almost all
developers avoid trying to build applications or products from scratch. Ever
present time-to-market pressure means end-product manufacturers and
application engineers increasingly rely on existing examples and abstraction
layers wherever available to save time. This allows more focus on user
experience and coding at the higher application levels for integration into
final products, rather than spending time and effort on re-developing core
code such as low-level drivers, middleware and communication stacks. Focus on
end-product user experience and differentiation are key drivers for today’s
product development efforts, so reference applications are a key enabler for
fast and robust development on MCU and applications processor-based products.
NXP’s application enablement spans a wide range, from application notes
addressing a specific device feature to production-ready turnkey solutions
with custom-built reference hardware for specific use case that can be quickly
turned into end-products. Between these approaches to enablement lies a middle
ground, where a full application solution is needed as a reference, but with
full flexibility to adapt that reference to a customer’s own application
needs.
To address this need and complement the wide range of MCU and applications
processor products, NXP has added App SW Packs, providing real-world, complete
application software packages that are flexible enough to be leveraged into
customer products across various technology spaces by a broad audience.
Flexible NXP Application Software Packs
App SW Packs are a hybrid software bundle approach, offering a middle ground
between turnkey solutions and example application code. They can be leveraged
for productization (similar to turnkey solutions) but are also meant to be
accessible by a larger development audience with an open-source policy for
customized productization. Provided in a complete and easy to use package, App
SW Packs deliver a combination of drivers, middleware, communication stacks
and sample applications, along with comprehensive guides and training
materials (application notes, lab guides, training videos, etc.) to enable
fast developer ramp-up and smooth integration within products.
NXP is developing a range of App SW Packs, targeting machine learning,
connectivity, remote device management, voice and vision and other application
spaces.
Machine Learning-Based System State Monitor – App SW Pack
The first in the series of App SW Packs is a machine learning-based state
monitoring system for time-series data.
Given the complexities of machine learning, neural networks and deep learning,
coupled with the challenges to scale down to resource-constrained MCUs, ML
application development can be daunting. The ML-based System State Monitor App
SW Pack was created to simplify development of smart sensing applications that
rely on ML processing of time-series data to generate decisions without human
intervention.

This ML-based System State Monitor App SW Pack enables developers to develop
and deploy neural networks on MCU-based systems. This App SW Pack shows how to
create a fan vibration state monitoring and failure identification solution,
and also details how to validate and evaluate the performance of a model on an
MCU-based embedded target. It goes through a real use case (starting from t0)
and results in an ML model being deployed and evaluated on the embedded board,
demonstrating each step of the ML development:
- How to collect data and to build a custom comprehensive dataset
- How to define the architecture of a neural network and train a model
- How to validate and deploy the model on the embedded device
The ML-based System State Monitor App SW Pack was developed using the eIQ®
ML development environment and comes with software for MCUs, various ML
projects and helpful collateral (application note, lab guide and video,
training and validation dataset). The alignment with eIQ allows the ML-based
System State Monitor App SW Pack to take advantage of the essential baseline
enablement within the eIQ framework including the eIQ Toolkit, eIQ Portal and
MCU-based eIQ inference engines like DeepViewRT™, Glow and
TensorFlow™ Lite Micro.
