Abstract
Methods and systems are disclosed for routing and distributing interrupts in a multi-processor computer to various processing elements within the computer. A system for distributing the interrupts may include a plurality of logic devices configured in a hierarchical tree structure that distributes incoming interrupts to interrupt redistributors (redistribution devices). The system also includes plural processing elements, where each processing element has an associated bus address. A shared serial bus couples the redistribution devices and processing elements. Each of the redistribution devices is configured to transfer the incoming interrupts to at least one of the processing elements over the common bus, based on the bus address.
