高速缓存影响的航天器控制软件调度设计方法
Scheduling Design Method for Spacecraft Control Software with Cache
摘要
Abstract
The task scheduling of spacecraft control software becomes more difficult due to the execution time jitter caused by cache.To deal with this problem,a scheduling design method is proposed based on cyclic executive.The probability distributions of execution times are used to design different system modes with different reliability.Through the mode changes,the processor can be sufficiently utilized and a certain extent degree of reliability is guaranteed.The proposed method can provide useful reference for the task scheduling of spacecraft control software.关键词
