Summary:PROBLEM TO BE SOLVED: To provide a technology of accelerating processing, in an electronic controller with a plurality cores.SOLUTION: An ECU 3 includes a plurality of cores 11a, 11b sharing one AD converter 14. Each of the cores 11a, 11b includes a conversion instruction unit and a data acquisition unit. The conversion instruction unit is configured to cause the AD converter 14 to perform AD conversion processing. The data acquisition unit is configured to acquire conversion data from a memory 13 storing conversion data that is digital data generated by the AD conversion processing. The conversion instruction unit included in the first core 11a is configured to cause the AD converter 14 to generate conversion data used in the second core 11b in addition to conversion data used in the first core 11a.SELECTED DRAWING: Figure 1 【課題】複数のコアを備える電子制御装置において処理を高速化する技術を提供する。【解決手段】ＥＣＵ３は、１つのＡＤ変換器１４を共用する複数のコア１１ａ、１１ｂを備える。複数のコア１１ａ、１１ｂのそれぞれは、変換指示部と、データ取得部と、を備える。変換指示部は、ＡＤ変換器１４にＡＤ変換処理を行わせる。データ取得部は、ＡＤ変換処理により生成されたデジタルデータである変換データが記録されるメモリ１３から、変換データを取得する。第１のコア１１ａが備える変換指示部は、第１のコア１１ａで用いられる変換データに加え、第２のコア１１ｂで用いられる変換データを、ＡＤ変換器１４に生成させる。【選択図】図１
