[0023] The present invention will be further described in detail below with reference to the drawings and embodiments.
[0024] The basic idea of the present invention is to configure a dynamic loading area in the hardware platform of the IMA system. The dynamic loading area is located in the core operating system layer area and is independent of the memory area of each partition. Its size is larger than the size of all the partition applications that need to be loaded later. sum. The memory addresses of each partition application are mapped to the memory space sequentially and adjacently. Store the application image files (such as app2.bin, app3.bin, app4.bin, etc.) that need to be loaded later in an external storage medium (such as removable disks, local Flash, remote PCs, etc.). Develop a multi-partition application loader, which is integrated into the core operating system as a component. When the IMA system is running, it responds to an external event interrupt. The int...
