    • 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.
    • 提供了用于多核系统的直接存储器访问(DMA)设备以及DMA设备的操作方法。 DMA设备包括信道状态确定单元,用于确定源信道和目的信道中的至少一个信道是否可用,源信道是在源核心和DMA设备之间形成的,目的信道是在目的地之间形成的 核心和DMA设备;以及数据传输处理单元,用于当源信道和目的信道都被确定为可用时,处理要发送到目的地核心的源核心的数据。
