Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] Existing analysis methods for dynamic reconfiguration of IMA systems are limited to simply generating configuration files with models containing configuration information, and directly analyzing the schedulability and resource constraints under different configurations through configuration information simulation, and can only judge the dynamic reconfiguration of the system. Whether the configuration meets the functional requirements and single characteristic indicators such as reliability and real-time performance cannot automatically generate a suitable dynamic reconfiguration configuration scheme according to the overall requirements of the system. The present invention aims at the requirements of high reliability and complete performance that the IMA system should achieve after dynamic reconfiguration. On the basis of establishing an IMA sys...

Abstract

The invention discloses a dynamic reconfiguration strategy optimization method of an IMA system based on a genetic algorithm, which belongs to the field of comprehensive electronic system design. The invention uses the genetic algorithm technology to solve the problem of the configuration scheme state space explosion when the IMA system is dynamically reconfigured, and obtains an effective IMA system dynamic reconfiguration strategy by adding the IMA system reliability, real-time and static load balance analysis methods Model. By reconstructing the configuration code of the software, hardware and time configuration of the IMA system, it can be transformed into the AADL model of the IMA system configuration plan, and the reliability, real-time constraints and multi-dimensional load balance analysis of the IMA system can be carried out through the AADL model, and the analysis and optimization of the genetic algorithm can be obtained Lethal genes and fitness functions in . Through the genetic algorithm operation, the optimal dynamic reconfiguration configuration scheme of the IMA system can be effectively found.
