Initialize process control blocks. The initialization of PCB includes:
① Initialize identification information.
Fill in the identifier and parent process identifier assigned by the system, fill in the new PCB;
② Initialize the status information of the processor.
Point the program counter to the entrance address of the program, so that the stack pointer points to the top of the stack;
③ Initialize processing machine control information.
Set the status of the process as a ready state or a restless state. For priority, it usually sets it to minimum priority, unless the user put forward high priority requirements in a formula.
