PROBLEM TO BE SOLVED: To realize a process management system capable of speeding up linking to a ready queue and the processing of dispatching operation. SOLUTION: Upon inputting a process switching instruction, an execution process selection circuit 3 inputs priority execution information from a priority display register 7, calculates the highest priority existing as an executable process and compares the highest priority with current priority indicating the priority of a process being executed at present. In detecting an executable process of priority higher than that of the process being executed at present, the circuit 3 extracts corresponding process information from a ready queue 91 and newly stores the current process in the queue 91 as an executable queuing process and a ready process control circuit 4 stores the process allowed to be newly executed on the basis of a ready request and detailed information from an interruption detection circuit 1 in the queue 91.
