Abstract

The invention discloses an embedded software system, and relates to the technical field of software development. The embedded software system comprises a hardware layer, a basic real-time kernel layer, an operating system service layer and a user application layer which are sequentially connected from bottom to top, and the hardware layer is used for describing hardware resource conditions of theembedded system; the communication adaptation unit is used for further packaging a communication function interface in the operating system service layer to obtain unified initialization, and callingthe function interface; the operating system service layer is used for providing various system services for a user; source code components of the operating system service layer are added by a user according to needs, and finally a user component library is formed. The user application layer is used for deploying application software compiled by a client; and the application software calls the service layer API, is mounted on the operating system in a task form, and is scheduled and operated by the operating system. Through a source code assembly mode, the updating efficiency is improved, thecost is saved, and reading, debugging and modification are facilitated.

Description

technical field [0001] The invention belongs to the technical field of software development, in particular to an embedded software system. Background technique [0002] With the development of software technology, in the process of designing and implementing new software, historical projects play an increasingly prominent role as reference, and software reuse technology is particularly important. Currently, software developed under embedded real-time operating systems such as VxWorks, It is mostly implemented by process-oriented languages ​​such as C language, which has poor reuse and expansion performance; when undertaking complex tasks, the difficulty of software maintenance increases with the complexity of the task, so that a slight change in requirements will bring problems to the entire software. disastrous consequences. [0003] VxWorks: An embedded real-time operating system developed by American Wind River Corporation (WindRiver), widely used in national defense, ae...
