This project is a monolithic operating system kernel designed to serve as the foundational software layer for diverse computing architectures and embedded platforms. It manages core system services, including processor scheduling, memory allocation, and hardware resource distribution, to facilitate communication between user applications and physical hardware.
The kernel utilizes a hardware abstraction layer and platform-specific device trees to ensure consistent operation across a wide variety of processors and specialized computing devices. It supports dynamic functionality through loadable kernel modules and employs interrupt-driven device management to handle peripheral data requests asynchronously.
The system provides comprehensive capabilities for managing hardware peripherals and system resources, ensuring stability through virtual memory paging and process isolation. It is specifically optimized for embedded systems development, providing the necessary low-level drivers and interfaces to bridge software requests with external sensors and displays.
