采用各种算法和策略，始终保持系统行为的可预测性。即在任何情况下，在系统运行的任何时刻，OS的资源配置策略都能为争夺资源（包括CPU、内存、网络带宽等）的多个实时任务合理地分配资源，使每个实时任务的实时性要求都能得到满足。-Using a variety of algorithms and strategies, and always maintain the predictability of system behavior. In any case, at any time in the system is running, the OS resource allocation strategy is able to compete for resources (including CPU, memory, network bandwidth, etc.) the number of real-time tasks rational allocation of resources, so that each real-time tasks, real-time The requirements can be met.
