<P>PROBLEM TO BE SOLVED: To provide a data transfer system for suppressing deterioration in performance by reducing the frequency of retries. <P>SOLUTION: A data processor 1 is provided with: a transmission synchronization buffer 103 for storing data to be transmitted; and a read control means 110 for controlling read of data from the transmission synchronization buffer 103. A data processor 2 is provided with: a reception synchronization buffer 211 for storing received data; and a retry request generation means 213 for, when the data cannot be received since the reception synchronization buffer 211 is busy, requesting the retry of data transmission to the data processor 1. The read control means 110 obtains a reference time corresponding to the occurrence interval of the retry request, and controls read of data from the transmission synchronization buffer 103 based on the reference time. <P>COPYRIGHT: (C)2010,JPO&INPIT |
