Abstract:
An electronic control device comprises: a logic circuit capable of reconfiguring a plurality of arithmetic circuits including a first circuit and a second circuit; a reconfiguration control unit that performs reconfiguration of the arithmetic circuit and confirmation of the reconfigured arithmetic circuit based on a reconfiguration command; and a processing control unit that sends the reconfiguration command to the reconfiguration control unit, and that has an operation executed by the arithmetic unit. When a first reconfiguration command is received, the reconfiguration control unit performs reconfiguration and confirmation of the first circuit. When confirmation of the first circuit by the reconfiguration control unit is completed, the processing control unit has an operation executed by the first circuit. After completion of reconfiguration of the first circuit and until competition of execution of a designated process by the first circuit, the processing control unit sends a second reconfiguration command and starts reconfiguration of the second circuit by the reconfiguration control unit.
