ActuatorsSensors
IoT devices run on low-cost low-power
hardware (HW) that interacts with
physical elements through sensors and
actuators.
They rely on a software stack roughly
made of 3 layers:
- Firmware (FW) to control the HW
- Application software (SW) to deliver
the device’s functions with potentially
a GUI layer to interact with the user
- An intermediary middleware (MW)
layer that leverages the FW and
provides services used by the SW

several tasks.
Connected devices need to support
many connectivity, communications and

They leverage data streams and formats
for cloud-based analytics.
They may run multiple applications that

Bringing-up the full software stack on an
embedded device involves pain points at all
levels:
- Porting the FW to all possible combinations of
microcontroller architectures, board support
packages, compilers, native libraries
- Integrating all middleware libraries in order to
provide the services required by the
application
- Developing application software code

PC and mobile (smartphones & tablets)
industries have addressed those pain points
by:
- Standardizing the hardware so FW
porting effort is reduced
- Providing complete application platforms
with pre-integrated libraries and unified
API so developers can focus and invest
their time and effort on their business
applications
- Leveraging a large and common
community of developers with state-of-
the-art techniques and tools so
developments are more efficient

Mobile OS
One could think that mobile operating
systems could be leveraged for IoT.
But they require expensive high-end
processors and resources (e.g. memory).
IoT devices run on low-cost and resource-
constrained microcontrollers.
So there’s a mismatch between mobile OS
requirements and IoT hardware constraints.

VERTICAL
INTEGRATION
Embedded RTOS solutions
have efficiently addressed
FW bring-up on fragmented
hardware by providing
vertical integration layers
for each combination.
But they still require
integration work for the FW
and MW.
They do not provide ready-
to-use solutions for
enabling IoT and application
store SW capabilities.
Applications still need to be
ported from one vertical
silo to another, further
fragmenting developers
communities.

The MicroEJ® Operating System
leverages the best of both worlds:
- The scalability of embedded RTOS
solutions for FW bring-up
- The large community of mobile &
PC developers for efficient SW
applications development
It provides APIs both for FW
integration and SW app development.
It enables horizontal integration of
middleware thanks to a virtualization
layer that isolates MW/SW layers from
FW/HW layers.

Middleware doesn’t need to be

requirements and optimize the HW bill
of materials.
Application developers can concentrate
their time and effort on creating value-
add products with competitive
advantage.
The same SW application can run as-is
on all HW combinations, so derivatives
or new products can be created faster.
