摘要： A home gateway apparatus connected to intra-home terminal devices in a home network, has external interfaces to external terminals; internal interfaces to the intra-home terminal devices; a management table memory having management information to be sent and a destination address of the intra-home terminal devices; a management information memory to store the acquired management information; and a management information control unit to send the management information to the external terminal, based on the destination address stored in the management table, after acquiring the management information of the terminal device based on the management information to be sent stored in the management table. The home gateway apparatus can freely select a sending mode of the management information for every intra-home terminal devices, by setting the management table. Therefore, the gateway apparatus having an advanced versatility can be provided.

摘要： A DMA channel data quantity setting section sets a data transfer quantity of each of a plurality of DMA channels in accordance with a data quantity or a ratio in advance. A channel select control circuit determines whether each DMA channel is active. A data transfer control circuit transfers the data of the DMA channel determined to be active by the channel select control circuit in accordance with the data transfer quantity of each DMA channel set by the DMA channel data quantity setting section. By doing so, a plurality of DMA requests are accepted per bus hold request, and the number of bus management right arbitration procedures and the latency between the channels are decreased.
