Absrtact: Process scheduling is one of the most important parts of the operating system, in this paper, we mainly explain the process model, the data structure involved, how to go from the kernel state to the user process. This section mainly completes the analysis of the process data structure, and the content from the beginning of the ring0>>ring1 process. 1. ProcessLet's take a look at what data struc

Why do I need a file system?Disks are characterized by high capacity, low cost, and persistence, and the data on the disk is not lost even if a power outage occurs. However, it is very difficult for the average user to use the disk because they do not know how to drive a disk and calculate where the data is stored on disk. As you can see from the previous disk basics, understanding the technical details of the disk will overwhelm the user.The

System ResourcesThe RTX kernel identifies a task process through the task Process Control module. This module is a dynamically allocated memory unit that stores all the control and state variables of the task process. When a task process is created by calling the os_tsk_create or os_tsk_create_user function, the corresponding TCB is created.The amount of memory that the TCB occupies, as defined in rtx_config.c .The RTX kernel assigns its own stack to

As we all know, CPU is the fastest part of the computer system, while external devices are the slowest part. There is a big difference between them. However, the CPU may always require access to peripherals. If each CPU operation has to wait for the completion of the peripherals, the valuable running time of the CPU will be greatly wasted. With the development of modern computer technology, most modern operating
