METHOD AND APPARATUS FOR HIGH SPEED CROSS-THREAD INTERRUPTS IN A MULTITHREADED PROCESSOR |
摘要 |
A multithreaded processor includes an interrupt controller for processing a cross-thread interrupt directed from a requesting thread to a destination thread. The interrupt controller in an illustrative embodiment receives a request for delivery of the cross-thread interrupt to the destination thread, determines whether the destination thread of the cross-thread interrupt is enabled for receipt of cross-thread interrupts, and utilizes a thread identifier to control delivery of the cross-thread interrupt to the destination thread if the destination thread is enabled for receipt of cross-thread interrupts. The requesting thread requests delivery of the cross-thread interrupt to the destination thread by setting a corresponding interrupt pending bit in a flag register of the multithreaded processor.; The destination thread is enabled for receipt of cross-thread interrupts if a corresponding enable bit is set in an enable register of the multithreaded processor. The flag and enable registers may be implemented within the interrupt controller. |
