1. An interrupt management system connected to an interrupt controller for managing a plurality of interrupts, the interrupt management system comprising:

  • a timer; and

    an interrupt management sub-system, connected to the timer, wherein the interrupt management sub-system is configured for;

    receiving the plurality of interrupts,determining a first interrupt of the plurality of interrupts to be a real-time interrupt,determining a second interrupt of the plurality of interrupts to be a non-real-time interrupt,determining the second interrupt to be at least one of a maskable interrupt and a non-maskable interrupt,initializing the timer for a predetermined time period based on the first interrupt,transmitting the first interrupt to the interrupt controller,queuing the second interrupt during the predetermined time period when the second interrupt is a maskable interrupt, andtransmitting the second interrupt to the interrupt controller when the second interrupt is a non-maskable interrupt.
