UCOIII time slice rotation scheduling

Premise: Time slice rotation method: mainly used for process scheduling in time-sharing system. In order to realize rotation scheduling, the system arranges all ready processes into a queue first process according to the principle of first in first out, and lets it run a time slice on the CPU. Time slice is a small time unit, usually in the or ...
