3. Embedded Devices
• Smart devices need to be able to acquire, compute and store data, and
perform several tasks
– Peripherals, processors (MCU, FPU, DSP), RAM, flash…
• Connected devices need to support many connectivity, communications and
security standards
– Physical/Link: 802.15.4, 868-902 MHz, 802.11, Bluetooth, cellular 2G/3G/4G…
– Network/Transport: Wi-Fi, 6LowPAN, TCP/UDP-IP, TLS/DTLS, ZigBee, Z-Wave…
• Interactive devices provide graphical and touch interface
– Graphical User Interface (GUI), Human-Machine Interface (HMI)
• Managed devices allow software content update and operations management
from the Cloud
– Over-The-Air (OTA) firmware update
– Device Management (DM)
• May use proprietary communication protocols over standard links
– Sensors, actuators, I/Os (GPIO, PWM, DAC/ADC, USB, I2C, SPI, UART…)
– Internet client/server (sockets)

4. IoT Devices
• IoT devices use standard frameworks and agents for communicating with
each other and connecting to services in the cloud that provide software
content and operations management
– TLS, HTTPS REST…
– Thread, AllJoyn, DDS, XMPP, AMQP, MQTT, CoAP, LWM2M…
• They leverage data streams and formats for cloud-based analytics
– XML, JSON…
• They may run multiple applications that can be dynamically downloaded
and installed/uninstalled (without FW update)
– User experience similar to smartphones/tablets = application store

6. • Embedded RTOS solutions have
efficiently addressed SW bring-up on
fragmented hardware by providing
vertical integration layers for each
combination (ISA/compiler/libs)
• But they may require integration
work for the BSP and native libraries
• They may not provide ready-to-use
solutions for enabling IoT and cloud-
ready SW capabilities
• Applications still need to be ported
from one vertical silo to another,
further fragmenting developers
communities

7. • The MicroEJ® Operating System
leverages the best of both worlds:
– The scalability of embedded
RTOS solutions for SW bring-up
– The large community of mobile &
PC developers for efficient SW
applications development
• It provides APIs both for
BSP/RTOS/libs integration and SW
app development
• It enables horizontal integration of
OS services thanks to a virtualization
layer that isolates application layers
from lib/RTOS/BSP/compiler/ISA
layers

#IoTDevCon
ADVANTAGES HOW:
Hardware independence
• True Portability of BINARY SW across HW (no
recompilation needed)
Micro-Virtualization layer (30KB)
• Formal Separation between HW-dependent-SW and
HW-independent-SW
Safe SW programming & execution Build & runtime checks, Sandboxing
Full set of SW foundation blocks High-level API & stacks
Secured investments
• Legacy code integration
Multi-language support: Java, C/C++ / ASM
Future-proof
• SW updates
• New SW downloads
Multi-application framework
• Build-time configuration
• Run-time add-ons
