Title:
ELECTRONIC CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/009115
Kind Code:
A1
Abstract:
The present invention makes it possible to reduce the communication data volume needed to update the configuration of a circuit unit of a reconfigurable circuit device. In an in-vehicle control system 10 provided with an FPGA 3, the FPGA 3 is configured so as to comprise: a circuit unit having a reconfigurable circuit; a transfer check unit which includes a circuit SRAM for storing configuration information of the circuit unit and which acquires a difference command relating to a change portion of a circuit element of the circuit unit; and a data conversion unit 4 which updates the configuration information on the basis of the difference command. In addition, the in-vehicle control system 10 is further provided with a non-volatile memory 6 for storing the configuration information stored in the circuit SRAM. The data conversion unit 4 may update the configuration information stored in the non-volatile memory 6 on the basis of the difference command acquired by the transfer check unit.
