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)

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

• 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

• 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 virtualizationlayer that isolates application layers from lib/RTOS/BSP/compiler/ISA layers

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
