PROBLEM TO BE SOLVED: To detect improper data caused by SEU while suppressing circuit scale or power consumption.SOLUTION: An improper data detection device 1 includes: a check data setting section 13 which sets check data for SEU detection to a packet formed of one or more word each having a predetermined word width; a packet transfer section 11 which generates a transfer packet by adding the check data for SEU detection to the packet; and an outside packet transmission section 12 which detects improper data on the basis of a value of the check data for SEU detection added to the transfer packet and a value of the check data for SEU detection supplied from the check data setting section 13, generates a transmission packet by excluding the check data for SEU detection from the transfer packet, and transmits the transmission packet to the outside. In the case where the values of the two pieces of check data for SEU detection are not matched, the outside packet transmission section 12 determines that improper data occurs. |
