    摘要: A centralized interrupt controller with a single copy of APIC logic provides APIC interrupt delivery services for all processing units of a multi-sequencer chip or system. An interrupt sequencer block of the centralized interrupt controller schedules the interrupt services according to a fairness scheme. At least one embodiment of the centralized interrupt controller also includes firewall logic to filter out transmission of selected interrupt messages. Other embodiments are also described and claimed.
