To reduce a used area of a logic circuit without largely lowering accuracy of calculation.SOLUTION: A calculation system includes a server and an on-vehicle device mounted on a vehicle. The server includes a server storage part which stores a learned model, a simplification part which generates contraction information determining accuracy of calculation using the learned model and an inference object, and server communication which transmits the contracted information to the on-vehicle device. The on-vehicle device includes a signal input part to which an output signal of a sensor mounted on the vehicle is input, an on-vehicle communication part which receives the contraction information, an inference part which performs an inference of the output signal that is a target and a logic circuit which enables re-constitution, and a re-constitution part which generates the inference part on the logic circuit based on the contraction information.SELECTED DRAWING: Figure 2

    【課題】演算の精度を大きく低下させることなく論理回路の使用領域を削減できる。【解決手段】演算システムは、サーバと車両に搭載される車載装置とを備える。サーバは、学習済モデルを格納するサーバ記憶部と、学習済モデルおよび推論対象を用いて演算の精度を定める縮約情報を作成する簡易化部と、縮約情報を車載装置に送信するサーバ通信とを備える。車載装置は、車両に搭載されたセンサの出力信号が入力される信号入力部と、縮約情報を受信する車載通信部と、出力信号を対象とする推論を行う推論部と再構成可能な論理回路と、縮約情報に基づき論理回路に推論部を作成する再構成部とを備える。【選択図】図2
