Embodiment 1

[0034] Such as figure 2 , taking the ARM hardware platform as an example, first select the corresponding operating system, such as Linux. Select the corresponding operating system adaptation module according to the Linux system, including the encapsulation of system calls such as semaphore, message queue, process and thread of the Linux system; and then select the corresponding middleware according to the specific application requirements of the system. The optional middleware includes common modules such as memory management, timer management, scheduling management, system monitoring, file management, exception handling, and network management. Scheduling management, system monitoring, and exception management are mandatory modules, and other modules can be configured according to requirements. For example, the system needs to implement timer and network functions, then put these two modules and the first few mandatory modules in the makefile to compile the system together,...

Abstract

The invention relates to the field of a software support platform, and particularly relates to an embedded software support platform which employs a middleware technology and a virtual machine principle, and adapts with different hardware platforms and operation systems. The embedded software support platform comprises a board support packet, an operation system adaption layer, and a public module; a commercial operation system is built on the board support packet; the operation system adaption layer is built on the commercial operation system; the public module is built on the operation system adaption layer; the public module provides a support function for an upper application program for task or thread encapsulation, semaphore encapsulation, message queue encapsulation and file system encapsulation, and shields the difference between different hardware platforms and operation systems. The software support platform disclosed by the invention is separated from the development of the upper application system; the development of the application system gets rid of high dependence on the operation system; the transplantability of the upper application system is effectively improved, and instantaneity of the system is improved through functions of a memory management module, a file management module and a timer management module.

Description

technical field [0001] The invention relates to the field of software support platforms, in particular to an embedded software support platform that adopts middleware technology and virtual machine principles and adapts to different hardware platforms and operating systems. Background technique [0002] The current embedded hardware platforms are generally produced by different manufacturers, and their system architectures are different and incompatible with each other. Although there are various commercial embedded operating systems to shield the differences between embedded hardware platforms, different operating systems provide resources and services in different ways, resulting in inconsistent interfaces of the resources and services provided, resulting in different Embedded application systems developed on top of existing operating systems have poor portability, and developers need to understand a lot of underlying software and hardware knowledge, and different solution...
