Abstract

The embodiment of the invention provides a real-time operating system architecture, a real-time kernel access method and a device. The architecture of the real-time operating system comprises a bottomreal-time kernel, at least comprising a middle layer of a file system, an upper application program, and a kernel common interface layer arranged between the real-time kernel and the middle layer, wherein the bottom real-time kernel comprises a middle layer of a file system, an upper application program, and a kernel common interface layer arranged between the real-time kernel and the middle layer. The kernel common interface layer provides a unified kernel common interface to the middle layer, so that the upper application can access the real-time kernel of the real-time operating system through the kernel common interface called by the middle layer. As that kernel common interface lay is added between the real-time kernel and the middle lay, By providing a unified kernel common interface to the middle layer, the difference between different types of real-time kernels can be shielded, so that applications developed for the unified kernel common interface can be applied to different types of real-time kernels, thereby improving the portability of applications and reducing the repetitive development of applications.

Description

technical field [0001] The embodiments of the present invention relate to the field of operating systems, and in particular to a real-time operating system architecture, a method and a device for accessing a real-time kernel. Background technique [0002] A real-time operating system (Real Time Operating System, referred to as RTOS) means that when external events or data are generated, it can accept and process them at a fast enough speed, and the processing results can control the production process or An operating system that responds quickly to the processing system, schedules all available resources to complete real-time tasks, and controls the coordinated operation of all real-time tasks. [0003] Usually, the real-time operating system adopts a hierarchical design. On the hardware layer composed of the CPU platform, it includes the real-time kernel at the bottom layer, the middle layer composed of the file system and the graphics system, and the application program at...
