So the process Management module is not part of the microkernel. Process Management-Manage process creation, destruction, and process attributes such as UID and GID memory management-manage a range

the time of the Interrupt Service program execution and reduce the scheduling wait time, the best way to implement the ISR in the operating system is to set the flag to construct a short ISR when the interrupt occurs, and the other work to create the corresponding thread to execute separately. It's like someone calls you, and when you suddenly get a mission instruction, you spend a lot of time on the phone while you're on the telephone, or you hang up and do a specific task.

Before and we introduced the method of thread synchronization on QNX Metux and Semophore, two methods can be used to lock one or several resources to avoid conflict of resource usage. In another case, a thread needs to use the thread synchronization method, barrier, to continue execution after another thread has finished working.To give a realistic example, suppose there are three soldiers operating an antiaircraft gun, one responsible for filling she
