Abstract: Multicore era, the main challenge of multi-processing system is inter-core communication. By studying the existing distributed and shared communication structure, this paper proposed the idea that using a distributed crosspoint-queued(CQ)instead of the traditional shared communication structure meanwhile handshaking by interrupt mechanism. An architecture of inter-core Communication using interrupt mechanism for multi-core DSPs is designed. From a system perspective, this design is compared with shared memory communication structure, the result shows that the designed is more efficient than the shared structure, especially when there are large amounts of data to transfer.
