What is the interrupt priority?

Interrupt priority refers to the order in which interrupt requests should be processed when multiple interrupt requests occur at the same time. When multiple interrupt requests arrive at the same time, the system needs to determine which interrupt to process first based on the interrupt priority. Interrupt priority is usually set by hardware or software. In hardware priority, each interrupt signal line has a corresponding hardware interrupt priority, and interrupt requests with high priority will be responded to first. In software prioritization, the operating system or program sets the priority of interrupts programmatically.

What is the interrupt priority?

Interrupt priority is the hardware that divides interrupt sources into several levels; in order to enable the system to respond in time and handle all interrupts that occur, the system divides the interrupt sources into several levels based on the importance and urgency of the interrupt event, which is called For interrupt priority, there are multiple interrupt sources in the microcomputer system, and it is possible that two or more interrupt sources issue interrupt requests at the same time.

What does interrupt priority do?

The function of interrupt priority is to determine which interrupt request the system should process first when multiple interrupt requests arrive at the same time. When multiple devices or events send interrupt requests to the computer at the same time, interrupt priority is used to determine which interrupt should be processed. To ensure that the system can correctly respond to and handle various interrupt events.
