Explain the different sub-functions of Process Scheduling.
Process scheduling contains the subsequent sub-functions:
1. Scheduling: Chooses the process to be executed next on the CPU. The scheduling function uses information from the Process Control Block's and selects a process based upon the scheduling policy in force.
2. Dispatching: Sets up execution of the chosen process on the CPU. Such function involves setting up the execution environment of the process that are selected, and loading information from the PSR and registers fields of the selected into the CPU.
3. Context saves: Saves the status of a running process while its execution is to be suspended. This function executes housekeeping whenever a process releases the center processing unit or is pre-empted.
The demonstrated diagram illustrates the use of scheduling sub functions:
Occurrences of an event invoke the context save function. The kernel instantly processes the event which has occurred. The scheduling function is instantly invoked to select a process for execution upon the CPU. The dispatching function arranges execution of the selected function on the center processing unit.
