EoS — Embedded Operating System
EoS is the foundation embedded operating system at the heart of the EmbeddedOS stack — a tightly-engineered real-time kernel with a unified hardware-abstraction layer and product-profile system that lets one codebase target everything from microcontrollers to server-class SoCs.
What EoS is
EoS provides a deterministic real-time scheduler, a clean process and IPC model, a unified Hardware Abstraction Layer covering 33 peripheral classes, and 41 ready-made product profiles spanning sensor nodes, gateways, infotainment, robotics, and edge servers.
Where Linux is too heavy and bare-metal is too primitive, EoS gives you a small, predictable kernel with the modern primitives — capability-based security, hot-pluggable drivers, deterministic interrupts — that production embedded systems actually need.
Features
The shape of EoS at a glance.
Real-Time Scheduler
Microsecond-class deterministic scheduling with priority inheritance and bounded-latency guarantees.
Unified HAL
33 peripheral classes (GPIO, I²C, SPI, UART, CAN, USB, Ethernet, DMA, ADC, …) abstracted across all supported MCUs and SoCs.
Product Profiles
41 turn-key configurations: sensor node, gateway, robot controller, infotainment, edge server, and more.
SMP & AMP Multicore
Run symmetric or asymmetric multicore on the same kernel — pin RTOS to one core, Linux on another.
Capability Security
Object-capability model for processes, drivers, and IPC ports — no ambient authority, no surprise privilege.
Hot-Plug Drivers
Load and unload drivers at runtime; safe rebinding without reboot.
Tiny Footprint
Kernel + scheduler + HAL fits in < 64 KB on Cortex-M devices, scales to multi-GB SoCs.
Open Standards
Apache 2.0 licensed, POSIX-leaning APIs, integrates with Zephyr/FreeRTOS drivers via shims.
Production-Ready
MISRA-aligned coding standard, CI fuzzing, formal verification of critical paths.
Open source on GitHub
EoS is Apache-2.0 licensed and developed in the open. Issues, discussions, and pull requests welcome.
