轮转法调度(round-robin,RR) 专门为分时系统设计。它类似于FCFS调度,但是增加了抢占以切换进程。定义一个较小的时间单元,称为时间片(time quantum,or time slice)。将就绪队列作为循环队列。CPU调度程序循环就绪队列,为每个进程分配不超过一个时间片段的CPU。
4. Round Robin Scheduling Theround robin schedulingalgorithm is designed for a time-sharing system in which a small time is defined termed as time quantum. A time quantum is generally from the 10 to 100 milliseconds. For implementing the RR scheduling the CPU scheduler keeps the process for th...
In time shared system, Round Robin (RR) scheduling gives optimal solution but it may not be suitable for real time systems because it gives more number of context switches and larger waiting time and larger turnaround time. In this paper two processor based CPU scheduling (TPBCS) algorithm ...

时间片轮转调度算法RR(Round Robin) 分配给调度上CPU的进程,确定了允许该进程运行的时间长度。每个进程会被分配一个时间片,在这个时间片的时间段内,允许进程运行;如果在时间片结束时该进程还在运行,就会剥夺该进程得而CPU并分配给另一个进程;如果该进程在时间片结束前终止或者阻塞,则CPU会立即完成任务并进行切换。这...
