PROBLEM TO BE SOLVED: To improve communication efficiency when occurring of a communication error in data transfer. SOLUTION: When image data is read from a memory 1 and written to an HDD 4, an HDD I/F 3 accumulates the image data transferred by a DMAC 2 in a retry buffer, and writing of the image data to the HDD 4 is performed after completion of accumulation for one transfer portion of data. If a serial communication error occurs at that time, the image data accumulated in the retry buffer within the HDD I/F 3 is retransmitted. COPYRIGHT: (C)2009,JPO&INPIT |
