Interrupt is subdivided into system and user interrupts owing to different characteristics of interrupt request and response method. Interrupt source management, interrupt vector management, interrupt nesting and clock tick interrupt management have all been implemented by hardware. The simulation results show the feasibility and stability of this kind of interrupt management method. In a word, the implementation of interrupt management by hardware improves not only the utilization rate of CPU, but also the real-time performance of the whole system.]]>Mooney, V.J. and D.M.
