Abstract
An object of the present invention is to provide a general-purpose data transfer apparatus which enhances the operation efficiency of a data processing apparatus without a large-scale increase of circuits and has the same interface with respect to respective channels. A data transfer apparatus which selects a specific channel from among a plurality of channels connected thereto and outputs data from a data processing apparatus, has a first path which transfers data to a channel via an output buffer, and a second path which transfers data to a channel without the output buffer intervention, the data transfer apparatus comprising a data selection circuit which connects these two paths to different channels, respectively; and a transfer control circuit which controls data transfer of the two paths.
