The invention relates to the field of computer airborne embedded software, particularly a task security sharing method of a large aircraft comprehensive treatment platform. The task security sharing method comprises the following specific steps: 1) analyzing system functions required to be integrated in the large aircraft comprehensive treatment platform; 2) formulating a partitioning principle to partition the system functions; 3) selecting a partitioned operating system to perform quota management to the partitions partitioned by the system; 4) encoding and debugging the application software in each of the partitions, so as to realize task security sharing. The task security sharing method disclosed by the invention solves the problem that the multi-task under the tablet manner cannot be isolated or protected to cause potential security hazards, realizes space and time isolation protection to the application partitions, improves the resource processing capability of the task security sharing at different security levels in the large aircraft comprehensive treatment platform, and improves the system security of whole aircraft.
Description
technical field [0001] The invention belongs to the technical field of computer software, and in particular relates to a task safety sharing method in a large-scale aircraft comprehensive processing platform. Background technique [0002] In the integrated processing platform of modern large aircraft, multiple subsystems are integrated on the same processing resource, sharing processing resources and IO resources. With the rapid development of processor capabilities, the software functions residing on the same processing resource are no longer single, and the scale is huge. Therefore, the system is required to be partitioned in time and space, and the software on the same module is decomposed into different critical levels. Builds are distributed in different partitions. Partitioning can reduce or eliminate the failure of one partition to the function and performance of another partition. If there is no partition, the highest critical level will be extended to the entire sy...
