Applications like GUI, computation, etc.

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

IoT devices use standard frameworks and agents for connecting to services in the Cloud that provide software content and operations management.

They leverage data streams and formats for cloud-based analytics.

They may run multiple applications that can be downloaded from an online store.

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

MOBILE PC

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

The embedded world is by nature fragmented and can’t rely on standardized hardware.

In these conditions, how to address the FW, MW, and SW pain points?What developers community can be leveraged in order to create IoT apps?

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.

VERTICALINTEGRATION

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.

HORIZONTALINTEGRATION

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 integrated nor ported but just configured to match device 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.
