摘　　要：为实现信号处理平台中应用任务的快速动态加卸载和智能切换,提出一种基于有序二叉决策图(OBDD)的智能加卸载算法。在分析智能加卸载整体系统构成的基础上,构建信号处理平台软硬件资源模型、态势参数定义字典和智能加卸载规则库。通过基于OBDD的智能规则决策算法,实现最小人工干预下的应用任务智能加卸载。实验结果表明,与顺序规则存储算法相比,该算法的效率较高,圈复杂度较低。In order to realize the fast dynamic loading,unloading and intelligent switching for application tasks in the signal processing platform,an intelligent loading and unloading algorithm based on Ordered Binary Decision Diagram(OBDD)is proposed.Based on the analysis of the whole intelligent loading and unloading system,the software and hardware resource model for the signal processing platform,situation parameter definition dictionary and intelligent loading and unloading rule database of signal processing platform are constructed.Through the intelligent rule decision algorithm based on OBDD,the intelligent loading and unloading for the application tasks under the minimum manual intervention is realized.Experimental results show that compared with the sequential rule storage algorithm,the proposed algorithm has higher efficiency and lower cyclomatic complexity.
