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 an IMA system dynamic reconfiguration strategy optimization method based on a genetic algorithm and belongs to the field of integrated electronic system design. According to the method, the problem of configuration scheme state space explosion during dynamic reconfiguration of an IMA system is solved by use of the genetic algorithm technology, and an effective IMA system dynamic reconfiguration strategy model is obtained by adding an IMA system reliability, instantaneity and static load balance analysis method. By performing reconfiguration coding on software and hardware and time configuration of the IMA system, the model can be converted into an IMA system configuration scheme AADL model, the reliability, instantaneity constraint and multidimensional load balanceanalysis of the IMA system is performed through the AADL model, and a lethal gene and a fitness function in genetic algorithm analysis optimization can be obtained. Through genetic algorithm operation, an optimal IMA system dynamic reconfiguration scheme can be effectively found.
