Title: CONTROL DEVICE AND METHOD FOR WRITING DATA TO CONTROL DEVICE
Abstract:
For improvement in production efficiency of a control device, the control device comprises: a first storage unit; a second storage unit which has a faster I/O speed than the first storage unit and has a first storage region and a second storage region in each of which it is possible to store a prescribed number of data blocks; and a control unit which, with either the first or the second storage region as a transfer destination region, causes a data block which has been transmitted from a write device to be stored in the transfer destination region, and transmits a verification value for the data block to the write device. If the transmitted verification value is proper, the write device transmits a block transmission commencement request to the control unit prior to transmission of the next data block. If the prescribed number of data blocks is stored in the transfer destination region and the block transmission commencement request has been received from the write device, the control unit switches the transfer destination region to the other of the first or the second storage region, and causes the prescribed number of data blocks which were stored in the transfer destination region prior to the switch to be written to the first storage unit.
