Abstract
A data transmission apparatus includes an output unit, when outputting data on a bus, to determine whether to output the data on the bus based on a result of a communication arbitration performed with competing data to be output on the bus, using priority information attached to the data; a storage unit to have areas set, the areas having respective priorities set for the communication arbitration, and to store a group of data having the consecutive priority information attached, in the respective areas; and a distribution unit to write the data having a transmission request received, in one of the areas in the storage unit, based on the priority information attached to the data. The output unit prioritizes outputting the data on the bus, the data being stored in the one of the areas having a higher priority, among the data stored in the areas.
