Embodiment Construction

[0067] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0068] In order to improve the reliability of communication between partitions, the embodiment of the present invention provides a partition communication method and device based on an embedded operating system. The embedded operating system can access the storage space of each partition and read the The content of the published message is stored locally, and the content of the message stored locally and subscribed by the partition can also be written into the stora...

Abstract

The invention relates to the technical field of embedded software, in particular to a partition communication method and device based on an embedded operating system, which is used to solve the problem of poor reliability in communication between partitions in the prior art. In the present invention, the message content to be published in the partition can be read by the embedded operating system and stored locally, and then when it is determined that the partition needs to subscribe to the message, the locally stored message content can be written into the storage space of the partition. The embedded operating system accesses the storage space of each partition, which can ensure that the partitions are isolated from each other. Even if one of the partitions is abnormal, it will not affect the interaction between other partitions and the embedded operating system, thus ensuring that other partitions can Normal operation improves the reliability of communication between partitions.

Description

technical field [0001] The invention relates to the technical field of embedded software, in particular to a partition communication method and device based on an embedded operating system. Background technique [0002] With the rapid development of embedded software technology, in some comprehensive modular embedded systems, the task of running subsystems with different functions on the same processor can be realized. Among them, each subsystem can be regarded as a partition, and each partition can be used as an independent application environment, and can independently run the application program. Moreover, the embedded operating system can manage each partition, which is embodied in: assigning different storage spaces to each partition to realize space isolation between partitions; adopting the scheduling strategy of time slice rotation, in a periodic scheduling process, for Each partition is assigned a fixed time window, and each partition can run under the assigned tim...
