Abstract
A direct memory access (DMA) management device and an operating method thereof are provided. The DMA management device is configured to decode a descriptor received from processors sharing a memory and divide the descriptor into sub-descriptors and transmit the sub-descriptors to DMA engines and transmit a result of parallel processing to a switches through at least one network port.
Claims20
A direct memory access (DMA) management device configured to:
- decode a descriptor received from any of multiple processors that are sharing a memory and based on the decoding divide the descriptor into sub-descriptors;
- and
- transmit the sub-descriptors to DMA engines and transmit a result of parallel processing to multiple switches through at least one network port.
A method of operating a direct memory access (DMA) management device, the method comprising:
- receiving a descriptor from processors sharing a memory;
- dividing the descriptor into sub-descriptors based on a result of decoding the descriptor,
- scheduling the sub-descriptors to an available DMA engine among the DMA engines according to statuses of the respective DMA engines;
- and
- transmitting a result of processing corresponding to the descriptor to switches through at least one network port based on whether processing of the scheduled sub-descriptors is completed.
