1. An information processing system, comprising:
a first information processing device that includes:
a first information processing unit configured to:
generate a first transfer parameter to control transfer of data, and
generate a second transfer parameter for reception of first transfer data,
a first direct memory access (DMA) control unit configured to:
control DMA based on the first transfer parameter, and
control transmission of the second transfer parameter to a second information processing device, and
a first communication unit, wherein
the first transfer parameter has a linked list structure,
the first transfer parameter includes a transfer source address of data, transfer destination address of data, and a link destination, and
the transfer destination address of data corresponds to a transmission channel address of the first communication unit; and
the second information processing device includes:
a second information processing unit configured to generate the first transfer parameter,
a second DMA control unit configured to:
control DMA based on the first transfer parameter,
control the reception of the first transfer data from the first information processing device based on the second transfer parameter, and
a second communication unit configured to communicate with the first communication unit.
