Abstract
The present invention makes it possible to reduce the volume of communication data necessary for updating the configuration of a circuit unit of a reconfigurable circuit device. In an vehicle control systemincluding an FPGA, the FPGAincludes a circuit unit including a reconfigurable circuit and a circuit SRAM that stores configuration information of the circuit unit. A transfer check unit that acquires a difference command regarding a change part of a circuit element in the circuit unit, and a data conversion unitthat updates the configuration information based on the difference command are provided. Further, in the vehicle control system, a non-volatile memorythat stores the configuration information to be stored in the circuit SRAM is further provided. The data conversion unitmay update the configuration information stored in the non-volatile memorybased on the difference command acquired by the transfer check unit.
