Synchronization of the system organizations to adopt quantitative signal P, V operation mechanisms control agencies include: (1) blocking and wake-up operation (2) the time slice interrupt handling procedures simulation time slice interrupt (3) the process scheduler is responsible for the process of allocation of processors. System involved in the three concurrent processes. The relationships between them are: (1) 3 process requires the use of critical resources mutex S2. (2) process 1 and process 2 has to be mutually exclusive use of critical resources S1. The system during operation were randomly print out the status of the process of transformation process, the system for the activation process and public variables changes.
