    Difference between Maskable and Non Maskable Interrupt

    Non-maskable interrupt

    Hardware interrupt
    In computing, a non-maskable interrupt is a hardware interrupt that standard interrupt-masking techniques in the system cannot ignore. It typically occurs to signal attention for non-recoverable hardware errors. Some NMIs may be masked, but only by using proprietary methods specific to the particular NMI. With regard to SPARC, the non-maskable interrupt, despite having the highest priority among interrupts, can be prevented from occurring through the use of an interrupt mask.

    When is an interrupt masked?
    An interrupt is said to be masked when it has been disabled or when the CPU has been instructed to ignore it. In this regard we have two classes of interrupts maskable and non-maskable interrupts. A maskable interruptis a hardware interrupt that may be ignored by setting a bit in an interrupt mask register’s (IMR) bit-mask.

    A maskable interrupt is a type of hardware interrupt that can be disabled or ignored by the CPU through specific instructions. This allows the CPU to prioritize certain tasks over others by selectively enabling or disabling these interrupts. Maskable interrupts are typically used for handling lower-priority tasks and can be either edge-triggered or level-triggered12.

    Key Characteristics

    1. Flexibility: Maskable interrupts provide flexibility as they can be selectively enabled or disabled, allowing more control over system performance1.

    2. Lower Priority Handling: These interrupts are useful for managing tasks with lower priority, giving the CPU time to focus on more critical processes1.

    3. Examples: Common examples of maskable interrupts include RST6.5, RST7.5, and RST5.5 in the 8085 microprocessor12.

    Learn the difference between maskable and non-maskable interrupts, two kinds of interrupts in the CPU. Maskable interrupts can be ignored by the processor, while non-maskable interrupts cannot be ignored and have higher priority.

  8. People also ask
    What is an example of a maskable interrupt?
    Examples include keyboard input, communication from peripheral devices, or other non-urgent events. Handling Time Variability is Acceptable: Maskable interrupts may have slightly longer handling times than non-maskable interrupts due to their flexibility.

    How does a non-maskable interrupt work?
    In the case of the occurrence of a Non-Maskable interrupt, the status and current instructions are suspended by storing them in a stack so that the CPU can handle the interrupt. Lower priority tasks can be handled through the Maskable interrupt. Tasks having high priority are handled by the Non-Maskable interrupt.

    When is a maskable interrupt processed?
    The maskable interrupt is processed immediately if the interrupt occurred has higher priority than currently executing instruction. Else the interrupt is processed after completing the current execution. The non-maskable interrupt has to be processed as soon as it occurs by suspending the current execution.

    What is the difference between maskable interrupts and NMIS?
    Maskable Interrupts can be temporarily disabled, while NMIs cannot. Maskable Interrupts are used for non-critical tasks, while NMIs handle crucial system events. Understanding these differences is crucial for operating system design and interrupt handling.

    How to masked a hardware interrupt?
    All maskable hardware interrupts ie. interrupts delivered to CPU by means of INTR signal (0-255) or through local APIC (16-255) can be masked as a group by using IF flag in the EFLAGS register. The INT n instruction permits interrupts to be generated by software.
