Claim Text:
1. A control device of an internal combustion engine that has a multicore processor including a plurality of cores mounted thereon, and is capable of performing various calculations relating to an operation of the internal combustion engine in parallel by the plurality of cores, comprising: calculation means that assigns a task of the calculations to at least one of the plurality of cores and performs calculations; 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, wherein the calculation means including: the control means stops the designated core or cores when the EGR operation is stopped, wherein the internal combustion engine comprises a turbo supercharger having a turbine installed in an exhaust passage, and a compressor installed in an intake passage, the EGR means includes means that controls HPL-EGR that recirculates a gas flowing in the exhaust passage at an upstream side from the turbine to the intake passage at a downstream side from the compressor, and means that controls LPL-EGR that recirculates a gas flowing in the exhaust passage at a downstream side from the turbine to the intake passage at the upstream side from the compressor, the assigning means assigns tasks of specific calculations relating to the HPL-EGR and the LPL-EGR respectively to different cores in the designated cores, and when at least one of the HPL-EGR and the LPL-EGR is stopped, the control means stops the designated core corresponding to the stopped EGR operation.
