Problems solved by technology

Usually, each application will be loaded into its partition together with the IMA module after it is powered on, which is called the static loading process, but sometimes it is not expected that the application will be loaded into its partition immediately after the IMA system is started want the app to run right away

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] The basic concept of the present invention is: configure a section of dynamic loading area in the IMA system hardware platform, this dynamic loading area is located in the core operating system layer area, independent from each partition memory area, its size is greater than all the partition application sizes that need to be loaded later sum. The memory addresses of each partition application are sequentially and adjacently mapped to the memory space. Store the application image files (such as app2.bin, app3.bin, app4.bin, etc.) that need to be loaded later in external storage media (such as removable disks, local Flash, remote PCs, etc.). Develop a multi-partition application loader, which is integrated in the core operating system as a component. When the IMA system is running, it responds to an external event interrupt. The interru...

Abstract

The invention discloses a loading method after multi-partition application of a comprehensive modularized avionics system. A section of dynamic loading area is set in the memory space; the dynamic loading area is divided into several areas, and each area corresponds to one; the interrupt response to an external event , sequentially load the corresponding application image files from the external storage medium to the configured dynamic loading area, and reset the working mode of the corresponding partition to cold start mode, so that the partition can host and run the application loaded later. Due to the adoption of the partition application post-loading technology, the corresponding partition applications can be selectively loaded according to actual needs during the operation of the IMA system, which saves IMA system resources. In addition, there is no need to wait for the real partition application to be built before performing IMA system synthesis. , improving the overall efficiency of the IMA system.

Description

technical field [0001] The invention relates to a loading method for partition application in a comprehensive modular avionics system, in particular to a loading method after partition application. Background technique [0002] With the development of avionics technology, modern aircraft gradually adopt advanced integrated modular avionics system (referred to as IMA system). Compared with the traditional combined avionics system, IMA system has many advantages, such as saving costs and reducing the weight of the aircraft itself. , Reduce power consumption, shorten development cycle, facilitate upgrade and maintenance, etc. At present, many military and civilian aircraft have adopted the IMA architecture, such as: Airbus's A380, Boeing's B777, B787, the US military's F-22, F-35, and the dismounted Comanche helicopter RAH- 66 etc. The IMA system is mainly composed of two components, one is the application, and the other is the IMA module. The application is used to realize ...
