Description: The NMI (Non-Maskable Interrupt) Handler is a critical routine in computer architecture that manages non-maskable interrupts in a system. These interrupts are events that require immediate attention and cannot be ignored by the processor, meaning the system must respond to them as a priority. The NMI handler allows the operating system or firmware to handle critical situations, such as hardware failures or error conditions, ensuring that appropriate measures are taken to preserve system integrity. In many computer architectures, the NMI handler is integrated into the processor design, enabling a quick and efficient response to these interrupts. Its implementation is essential for systems requiring high availability and reliability, such as medical devices, industrial control systems, and servers. The ability to handle non-maskable interrupts is a key component in ensuring that the system can react to unexpected events without compromising its overall operation.
