Data transfer control device and image forming apparatus

An image forming apparatus, comprising a data transfer control device, wherein

• the data transfer control device comprises:
• an acquisition section configured to acquire data from a plurality of processing sections for transmitting the data with a transmission path;
• an analysis section configured to analyze additional information of the data acquired by the acquisition section;
• a band detection section configured to detect a transmission band of the transmission path based on the additional information;
• a mask output section configured to output a request mask signal for suppressing the transmission of the data based on the transmission band detected by the band detection section and a target band preset on the transmission path;
• and
• a selection section configured to select the data transmitted on the transmission path among the data based on the request mask signal output by the mask output section.

A method of data transfer, comprising:

• acquiring data from a plurality of processing sections for transmitting the data with a transmission path;
• analyzing additional information of the acquired data;
• detecting a transmission band of the transmission path based on the additional information;
• outputting a request mask signal for suppressing the transmission of the data based on the detected transmission band and a target band preset on the transmission path;
• and
• selecting the data transmitted on the transmission path among the data based on the output request mask signal.
