Abstract
A data transfer method for matching an upper protocol layer to a high speed serial bus. In the data transfer method, it is determined whether transfer data to be transferred from the upper protocol layer to the high speed serial bus, is stream data that is transferred to a predetermined node which the bus can identify, and form data flow defined by a predetermined flow classifier. If the transfer data is determined to be stream data, a channel is allocated in the bus and the transfer data is transferred through the channel. However, if the transfer data is determined not to be stream data, the transfer data is transferred by an asynchronous transfer method according to the high speed serial bus standard, without allocating a channel. Due to a channel Matron of the high speed serial bus, an upper protocol layer of existing applications which do not specify a service to provide, can be effectively matched to the high speed serial bus.
