How to solve the problem of system interruption on win10 computer

1. How to solve the problem of system interruption on win10 computer? We can solve it through the task manager. Today, I will introduce the specific solution to the problem of system interruption on the win10 computer.

2. First, turn on the computer, enter the desktop, right-click in the blank space of the taskbar, and select the task manager option in the open menu. As shown in the figure, on the open Task Manager page, switch to the details option above.

3. Method 1: Repair the damaged file, press WIN+X and then select the command prompt (administrator) to execute the command: sfc/scannow to see if it can be solved;Or use the command to repair the Windows components.

4. Enter the BIOS to change the hard disk format from IDE to AHCI II. The main MBR boot of the hard disk is damaged, and the PE boot disk should be used to repair the boot.

5. Next, the editor will teach you how to solve the problem of 100% CPU occupation when the win10 system is interrupted. To disable the DiagTrackDiagnosticsTrackingService service, first press WIN+R on the keyboard to call up the run, and enter services.msc to return.

What is the specific function of the three statements of the interrupt system

The specific function of the three statements of the interrupt system isNext: Interrupt Priority: It is used to set the priority of different interrupt sources so that the system can handle interrupts according to priority when multiple interrupt sources occur at the same time. Interrupt enable: used to enable or disable certain interrupt sources in order to control the trigger of interrupts when necessary.

Realize human-computer connection: In the process of computer work, if the user wants to intervene in the machine, such as viewing the intermediate results of the calculation, understanding the working status of the machine, giving temporary commands to the machine, etc. These functions are almost impossible to be realized in a computer without interrupting the system.

void time0() interrupt 1 using 1 Suppose we call another delay() in the interrupt; this delay acts as a delay. Then, we need to make sure that the register group we use is the same group, otherwise, there will be confusion.

The interrupt system of the computer can enhance the CPU's ability to handle multitasking events. The interrupt mechanism is one of the infrastructures in modern computer systems. It acts as a communication network in the system to coordinate the system's response and processing of various external events. Interruption is a necessary condition for realizing multi-channel programming.

What is the implementation of the interrupt system

First of all, the CPU interrupt processing process pushes the PC value at the breakpoint (that is, the address of the next instruction to be executed) into the stack and retained, which is called the protection breakpoint, which is Dynamic execution. Then, push the relevant register content and flag bit status into the stack for retention, which is called protection site, which is completed by software execution.

Realized by hardware.3 Send the entrance address of the interrupt service program to the PC and switch to the interrupt service program. It can be realized by hardware or software. 4 Protect the site, set the shield word, and open the interrupt, that is, protect the content of some registers in the CPU, set the interrupt processing order, allow more advanced interrupt requests to be responded to, and realize interrupt nesting. Realized by software.

Interruption: means that when there is a need, the CPU temporarily stops the execution of the current program and instead executes the program and execution process to deal with the new situation. That is, during the operation of the program, there is a situation in the system that must be handled by the CPU immediately. At this time, the process of the CPU temporarily suspending the execution of the program and dealing with this new situation is called interruption.
