Provided are a multi-process device and an inter-process communication (IPC) method thereof. The multi-processor device includes a first processor, a second processor, a first memory connected to the first processor, and a second memory connected to the second processor. When an inter-process communication (IPC) operation is performed between the first processor and the second processor, data is exchanged between the first memory and the second memory.

Multi-processor device and inter-process communication method thereof

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.

Multi-processor apparatus using dedicated buffers for multicast communications

A data storage device includes a data storage device controller configured to control a storage medium, and a tag duplicate check unit to determine, when a frame is received from an initiator, the initiator, tag information, and a type of the sent frame and providing an interrupt to the data storage device controller if a same frame type and same tag information are received from a same initiator.
