<P>PROBLEM TO BE SOLVED: To provide an advanced programmable interrupt controller centralized with respect to a plurality of processing units. <P>SOLUTION: The centralized interrupt controller having a single copy of APIC (advanced programmable interrupt controller) logic provides all the processing units of a multi-sequencer chip or a system with APIC interrupt providing services. 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 has firewall logic for filtering out transmission of a selected interrupt message. Other embodiments are also written or requested. <P>COPYRIGHT: (C)2012,JPO&INPIT |
