针对传统串行空间碎片探测软件 DEBIE 存在的无法有效并行执行问题，设计和实现了 DEBIE 并行软件及 WCRT 计算方法。该并行设计采用处理单元划分、多线程执行等方法，并在构造的 MSC 语义图基础上，对共享缓存划分的最佳配置方式进行了优选。实验结果表明，该并行化方法是有效的，在真实环境和最坏情况下加速比均有显著的提升。

Aiming at the shortages such as that traditional space debris detection serial software-DEBIE cannot be effectively executed in parallel,this paper designed and implemented the DEBIE parallel software and the WCRT calculation method. The concurrent designing methods include unit division,multi-thread execution and so on.Based on the structure of MSC se-mantic graph,it optimized the optimal configuration of shared cache partitioning too.The experimental results show that the parallel method is effective,the speedups in the real environment and the acceleration of the worst cases have been improved respectively.
