【摘要】 主要提出了一种检测实时操作系统内存分配性能的方法,利用概率统计的方法随机产生内存碎片,检测实时操作系统在不同条件下内存分配性能的变化,并采用符合正态分布的随机数产生内存碎片,对嵌入式操作系统VxWorks的内存分配性能进行检测,最后结合实际数据分析了VxWorks的内存分配性能符合实时操作系统的要求,同时验证了该检测方法的可行性和可信性。更多还原

【Abstract】 This article discussed the method of testing the performance of RTOS’ memory allocation.It produced memory debris by utilizing the method of probability and statistics.Under the different conditions,it detected the changes of the RTOS’ memory allocation.The performance of VxWorks’ memory allocation was tested by using the memory debris which was produced by the normal random number.At last,its performance was analyzed based on the testing data.These data showed that the VxWorks was consistent with the requirements of RTOS.And it also validated the feasibility and credibility of this testing method.更多还原
