Description: Interrupt latency refers to the time elapsed from the occurrence of an interrupt in the system until the corresponding interrupt handler is initiated. This concept is crucial in real-time systems, where rapid response capability is essential for the proper functioning of critical applications. Latency can be influenced by various factors, including system load, interrupt priority, and microprocessor architecture. In a kernel mode environment, where the operating system has full access to the hardware, latency can be minimized through optimized interrupt management. On the other hand, in user mode, where applications have restricted access, latency may be higher due to the need to switch contexts between user mode and kernel mode. Interrupt latency is a key performance indicator of the system, as it directly affects the system’s ability to handle real-time events. In applications such as industrial control systems, autonomous vehicles, and medical devices, low interrupt latency is essential to ensure operational safety and effectiveness.<\/p>\n","protected":false},"excerpt":{"rendered":"
