Control circuit, information processing device, and method of controlling information processing device

An information processing device comprising:

• a data transmitting circuit for transmitting data;
• a data receiving circuit for receiving the data;
• and
• a control circuit connected to the data transmitting circuit and the data receiving circuit,
• wherein the control circuit includes:
• a data receiving unit for receiving data transmitted by the data transmitting circuit;
• a packet analyzing unit for judging whether the data received from the data transmitting circuit is a packet including history acquisition information in which an instruction for acquiring history information of transmission and reception of the data is set, and reading the history acquisition information from the received data upon judging that the received data is the packet including the history acquisition information;
• a history acquisition executing unit for starting or stopping acquiring the history information of the transmission and reception of the data according to the history acquisition information read by the packet analyzing unit to store the history information acquired;
• and
• a data transmitting unit for transmitting the packet including the history acquisition information or a packet other than the packet including the history acquisition information to the data receiving circuit as the received data.

A method of controlling an information processing device having a data transmitting circuit for transmitting data, a data receiving circuit for receiving the data, and a control circuit connected to the data transmitting circuit and the data receiving circuit, the method comprising:

• receiving the data transmitted by the data transmitting circuit;
• judging, by the packet analyzing unit of the control circuit, whether the received data is a packet including history acquisition information in which an instruction for acquiring history information of transmission and reception is set,
• reading the history acquisition information from the received data upon judging that the received data is the packet including the history acquisition information;
• starting or stopping acquiring the history information of the transmission and reception of the data according to the history acquisition information read by the packet analyzing unit to store the history information acquired;
• and
• transmitting the packet including the history acquisition information or a packet other than the packet including the history acquisition information to the data receiving circuit as the received data.
