Patent ID: 7493423

Claim:
A data transfer control device comprising: a node to which input data is received, the input data being transferred through serial transfer paths for first to pth channels, wherein p is a natural number greater than one; a logic circuit that splits the input data into predetermined units for the first to pth channels in sequence, and outputs thus-split data together with a split transfer notification code for each of the first to pth channels when split data transfer is performed, and outputs the input data without the split transfer notification code to one of the first to pth channels when the single data transfer is performed; first to pth parallel/serial conversion circuits that convert the data and the split transfer notification code that are outputted for the first to pth channels into serial signals; and first to pth output circuits that output the serial signals that have been inputted from the first to pth parallel/serial conversion circuits to the serial transfer paths for the first to pth channels.
