Abstract:
A Direct Memory Access (DMA) device for a multi-core system, and an operating method of the DMA device are provided. The DMA device includes a channel state determining unit to determine whether at least one channel among a source channel and a destination channel is available, the source channel being formed between a source core and the DMA device, and the destination channel being formed between a destination core and the DMA device, and a data transmission processing unit to process data of the source core to be transmitted to the destination core, when both the source channel and the destination channel are determined to be available.
