Abstract
(EN) The present invention provides an in-vehicle information processing device and an in-vehicle information processing method that can be expected to contribute to employing a multicore and shared-memory configuration in a device installed in a vehicle.　The in-vehicle information processing device according to the present embodiment includes a plurality of processing units that are installed in the vehicle and perform processing in parallel, and a plurality of shared storage units that are accessible by the plurality of processing units. The plurality of processing units perform exchange of information via at least one shared storage unit, and change the shared storage unit used for exchange of information at a predetermined timing. A detecting unit that detects abnormality of the shared storage units is provided thereto. The predetermined timing is a timing at which the detecting unit detects abnormality of the at least one shared storage units. In a case of the detecting unit detecting abnormality of the at least one shared storage units, the plurality of processing units may exchange information via a different shared storage unit.
(FR) La présente invention concerne un dispositif de traitement d'informations à bord d'un véhicule et un procédé de traitement d'informations à bord qui peuvent contribuer à l'utilisation d'une configuration de mémoire partagée et multicœur dans un dispositif installé dans un véhicule.　Le dispositif de traitement d'informations à bord d'un véhicule selon le présent mode de réalisation comprend une pluralité d'unités de traitement qui sont installées dans le véhicule et effectuent un traitement en parallèle, et une pluralité d'unités de stockage partagées qui sont accessibles par la pluralité d'unités de traitement. La pluralité d'unités de traitement effectuent un échange d'informations par l'intermédiaire d'au moins une unité de stockage partagée, et modifient l'unité de stockage partagée utilisée dans le cadre de l'échange d'informations à un moment prédéterminé. Une unité de détection qui détecte une anomalie des unités de stockage partagées est fournie à ces dernières. Le moment prédéterminé est un moment auquel l'unité de détection détecte une anomalie de ladite unité de stockage partagée. Dans le cas où l'unité de détection détecte une anomalie de ladite unité de stockage partagée, la pluralité d'unités de traitement peut échanger des informations par l'intermédiaire d'une unité de stockage partagée différente.
(JA) 車両に搭載される装置におけるマルチコア及び共有メモリの構成の採用に寄与することが期待できる車載情報処理装置及び車載情報処理方法を提供する。　本実施の形態に係る車載情報処理装置は、車両に搭載され、並列的に処理を行う複数の処理部と、前記複数の処理部がアクセス可能な複数の共有記憶部とを備え、前記複数の処理部は、少なくとも１つの共有記憶部を介して情報の授受を行い、所定のタイミングで、情報の授受に用いる共有記憶部を変更する。前記共有記憶部の異常を検出する検出部を備え、前記所定のタイミングは、前記検出部が前記少なくとも１つの共有記憶部の異常を検出したタイミングであり、前記複数の処理部は、前記検出部が前記少なくとも１つの共有記憶部の異常を検出した場合に、別の共有記憶部を介して情報の授受を行ってもよい。
