A DSP communication task scheduling system and method

Abstract

The invention discloses a DSP communication task scheduling system and method, which relate to the field of missile-borne application platforms, including S1, classifying communication tasks according to communication task functions and sub-modules of the DSP communication task scheduling system, and classifying each type of communication task Set the priority; S2, set the task scheduling system running state machine, and control the permission bit of the communication command of each communication task processing process; S3, when the task scheduling system receives the message, perform secondary Cache, set message classification and message response authority. The DSP communication task scheduling system of the present invention, through the improved design of the internal task system architecture, occupies less hardware resources and lower processing time delay than the existing communication task scheduling system, and can well meet the engineering application environment requirements of the missile-borne embedded platform .

Description

technical field [0001] The invention relates to the field of missile-borne application platforms, in particular to a DSP communication task scheduling system and method. Background technique [0002] At present, with the rapid development of informatization and intelligence of weapon equipment systems, the requirements for the functions and performance indicators of missile weapon systems are getting higher and higher, and the overall design of the system is obviously becoming more complicated. The design of the system architecture also puts forward higher requirements. [0003] According to the requirements of the modular design of the missile weapon system, the terminal guidance signal processing system of the missile-borne platform is decomposed into multiple subsystems, each system completes different tasks and functions, and the systems are connected and communicated in real time through multiple formats of communication interfaces. Complete the synchronous cooperation...

Problems solved by technology

At the same time, because the missile-borne application environment has high requirements on the real-time and stability of software operation, it is difficult for the existing task scheduling system to reasonably allocate and control multiple communication tasks in real time and stably. Problems such as thread mutual exclusion, communication deadlock, resource access conflict, and untimely command response make it difficult to meet the effectiveness of communication tasks and the reliability of system operation
