In an internal combustion engine that performs calculation processing by using a multicore processor having a plurality of cores, efficient distribution of cores for use corresponding to a calculation load of the internal combustion engine is performed. A control device of an internal combustion engine, which has a multicore processor including a plurality of cores mounted thereon and is capable of calculating various calculations relating to an operation of the internal combustion engine in parallel by the plurality of cores, includes calculation means that assigns a task of the calculations to at least one of the plurality of cores and performs the calculation, EGR means that controls an EGR operation that recirculates a gas flowing in an exhaust system of the internal combustion engine to an intake system, and control means that decreases a number of cores that are used in the calculation means to be smaller as compared with before stop, when the EGR operation is stopped. The calculation means includes assigning means that assigns a task of a specific calculation relating to the EGR operation to one or a plurality of designated cores, and when the EGR operation is stopped, the control means stops the designated core or cores. |
