Contiki
Contiki is an operating system designed for resource-constrained embedded devices and the Internet of Things. It provides a lightweight, event-driven kernel that enables multitasking and low-power wireless network connectivity on hardware with extremely limited memory and processing power.
The system distinguishes itself through a stackless threading model that allows for a blocking-style programming interface while maintaining a minimal memory footprint. It supports dynamic module and firmware management, enabling the loading and linking of relocatable binary code at runtime to update application functionality without requiring a full system reboot.
The platform includes a modular hardware abstraction layer to ensure portability across diverse low-power processor architectures. It also features a specialized networking stack that utilizes static memory allocation and buffer reuse to provide reliable communication. Additionally, the system supports both local graphical output and remote interface rendering by streaming visual data over network protocols.
