A DSP communication task scheduling system and method

Abstract

The invention discloses a DSP communication task scheduling system and method, and relates to the field of missile-borne application platforms, and the method comprises the steps: S1, carrying out theclassification according to the communication task function and the communication task of each sub-module of the DSP communication task scheduling system, and setting the priority of each type of communication task; S2, setting a task scheduling system running state machine, and performing permission bit control on a communication instruction of each communication task processing process; and S3,when the task scheduling system receives the message, performing secondary caching on the received message, and setting message classification and message response authority. Compared with an existing communication task scheduling system, the DSP communication task scheduling system has the advantages that through the improved design of the internal task system architecture, less hardware resources are occupied, the processing time delay is low, and the engineering application environment requirements of the missile-borne embedded platform can be well met.

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
