Single value interrupt signaling for large number of devices connected to an interrupt controller makes use of a data or address bus as a passive interrupt signaling connection offering very large numbers of interrupt values

摘要

Interrupt handling method for large numbers of devices connected to an interrupt controller. Using a data and or address bus as passive interrupt lines for carrying the IRQ descriptions increases the number of available interrupts. Independent claims are also made for interrupt handling methods, bus -type devices, interrupt handling hardware, operating systems, interrupt controllers, etc.
