Abstract: An apparatus includes a multiprocessor including a plurality of processors including respective memories. Each of the memories has a dedicated storage location for multicast messages. At least one bus is coupled in common to the plurality of processors. The apparatus further includes an IPC unit coupled to the at least one bus and configured to retrieve multicast messages from the dedicated storage locations via the at least one bus and to selectively route the retrieved multicast messages among the plurality of memories.
