Title (EN) VEHICLE CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE DE VÉHICULE
(JA) 車両制御装置
Abstract:
(EN) The purpose of the present invention is to optimize efficiency during inter-core communication arising from cyclic interrupts by ensuring that load is not being focused on just some of the computation units. Provided is a vehicle control device comprising: a plurality of computation units 2, 3 for executing programs; a storage region 5 which the plurality of computation units 2, 3 cyclically access; and a sensor 8 for detecting external information. The plurality of computation units 2, 3 receive the external information detected by the sensor 8 and adjust a process involving the storage region on the basis of the external information received. The external information is the frequency of writes to a recording region 4.
(FR) L'objectif de la présente invention est d'optimiser l'efficacité pendant une communication inter-coeur provenant d'interruptions cycliques en garantissant qu'une charge n'est pas focalisée sur une partie seulement des unités de calcul. L'invention concerne un dispositif de commande de véhicule comprenant : une pluralité d'unités de calcul (2, 3) pour exécuter des programmes ; une région de stockage (5) à laquelle la pluralité d'unités de calcul (2, 3) accèdent cycliquement ; et un capteur (8) pour détecter des informations externes. La pluralité d'unités de calcul (2, 3) reçoit les informations externes détectées par le capteur (8) et ajuste un processus impliquant la région de stockage sur la base des informations externes reçues. Les informations externes sont la fréquence d'écritures dans une région d'enregistrement (4).
(JA) 本発明は、周期的な割り込み起因のコア間通信を行っているときに、一部の演算部に負荷が集中しないようにして利用効率を最適化する。プログラムを実行する複数の演算部2,3と、複数の演算部2,3が周期的にアクセスする記憶領域5と、外部情報を検出するセンサ8とを備え、複数の演算部2,3は,センサ8が検出した外部情報を受信し、当該受信した外部情報に基づいて、前記記憶領域に対する処理を調整する。外部情報は、記録領域4に対する書込み頻度である。
