Method and system for generating and delivering inter-processor interrupts in a multi-core processor and in certain shared memory multi-processor systems

摘要

Certain embodiments of the present invention are directed to providing efficient and easily-applied mechanisms for inter-core and inter-processor communications and inter-core and inter-processor signaling within multi-core microprocessors and certain multi-processor systems. In one embodiment of the present invention, local advanced programmable interrupt controllers within, or associated with, cores of a multi-core microprocessor and/or processors of a multi-processor system are enhanced so that the local advanced programmable interrupt controllers can be configured to automatically generate inter-core and inter-processor interrupts when WRITE operations are directed to particular regions of shared memory.
