Abstract

The invention discloses a unified inter-task communication method supporting multiple processors and a rocket communication method. The unified inter-task communication method supporting the multipleprocessors comprises that: a to-be-issued message is received; a corresponding sending link is selected according to a target task address, and the message is sent to the target task; before the corresponding sending link is selected, whether the processor is a single processor system or multiple processor systems needs to be judged, and when the processor is the single processor system, the target task can be identified by the priority of the processor; and when the processor is a plurality of processor systems, the target task comprises a processor (CPU) number and priority. Compared with the prior art, the method has the advantages of reasonable design and capability of supporting cross-operating system communication in the operating system.

Description

technical field [0001] The invention relates to an embedded real-time operating system, in particular to a unified inter-task communication method supporting multiple processors and a rocket communication method. Background technique [0002] Communication between different tasks is the basic function of embedded real-time operating system. The existing inter-task communication mechanisms in the operating system mainly include pipelines, semaphores, message queues, etc., while the communication mechanisms across operating systems (multiprocessor systems) include sockets, RPC (remote procedure calls), etc. [0003] The rocket multiprocessor system in the aerospace field has the characteristics of high real-time performance and multiple communication methods. The existing inter-task communication mechanism that supports multi-processors needs to be processed through the underlying network protocol stack, etc., and the controller has a large workload to process data, which aff...
