Abstract

The invention relates to an improved memetic algorithm-based project code module redundancy optimal distribution protection method. The method comprises the steps of 1, performing module-based multilevel segmentation on a project code to obtain a multilevel structure corresponding to the code; 2, encoding a solution of the multilevel structure and building a reliability model; and 3, solving the reliability model by utilizing an improved memetic algorithm, wherein an obtained optimal solution is an optimal redundancy set of modules in the multilevel structure. The improved memetic algorithm improves a crossover operator and a local search operator in a MA to improve the optimization precision and speed; and a higher-reliability solution can be obtained when a target model is optimized by utilizing the improved algorithm.

Description

technical field [0001] The invention belongs to the technical field of DSP system soft protection, in particular to a protection method based on an improved meme algorithm for optimal distribution of engineering code module redundancy. Background technique [0002] The vast space is full of various cosmic rays and particles: protons, electrons, alpha particles, gamma rays, heavy ions, etc. The radiation effect of these particles will have a serious impact on the electronic instrument DSP (digital signal processing) in the space environment: such as Single Event Effect (SEE: Single Event Effect), the main manifestations are: Single Event Upset (SEU: Single Event Upset), Single Event Transient Pulse (SET: Single Event Transient) and Single Event Disturbance (SED: Single Event Disturb), etc. The common characteristics of these phenomena are: the function node is uncertain, the fault state cannot be reproduced, and it has strong timeliness and concealment, which will have unpred...
