loongos is an industrial control operating system with streamlined, efficient, and real-time characteristics.

loongos is based on the general linux kernel and adopts rt-linux technology for real-time performance.

 

loongos simplifies the complex traditional x personal computer graphics system and supports the three graphics application modes of framebuffer, egl, and wayland. among them, framebuffer (two-dimensional) and egl(three-dimensional) are single-window application full-screen modes that feature lightweight, rapid startup, and convenient development. wayland mode supports multi-window applications and realizes a full-featured three-dimensional opengl driver and programming interface with a concise personal computer graphics environment. all the three graphics modes of loongos are able to support the qt programming development and application environment and to support the rtapi programming interface compatible with vxworks. according to the needs of embedded systems, loongos not only achieves the features such as file system reinforcement, power-down protection, partition protection, and security isolation but also flexibly customizes special systems according to requirements implemented by the integrated development environment ldk.
