Abstract
(EN)
Methods, apparatus, systems, and articles of manufacture are disclosed to synchronize data bus access. An example system includes a first computing device to transmit a first synchronization pulse to second computing devices using a first bus, the first synchronization pulse to synchronize first timers of the second computing devices to trigger a data schedule including one or more data cycles, and transmit a second synchronization pulse to the second computing devices using the first bus, the second synchronization pulse to synchronize ones of the first timers and slot counters of the second computing devices to trigger the one or more data cycles. The example system further includes the second computing devices to transmit data to the first computing device using a second bus during the one or more data cycles, where each of the one or more data cycles is assigned to a corresponding one of the second computing devices.

L'invention concerne des procédés, un appareil, des systèmes et des articles manufacturés visant à synchroniser un accès de bus de données. Un système donné à titre d'exemple comprend un premier dispositif informatique destiné à transmettre une première impulsion de synchronisation à de seconds dispositifs informatiques à l'aide d'un premier bus, la première impulsion de synchronisation visant à synchroniser de premiers temporisateurs des seconds dispositifs informatiques pour déclencher un programme de données comprenant un ou plusieurs cycles de données, et transmettre une seconde impulsion de synchronisation aux seconds dispositifs informatiques à l'aide du premier bus, la seconde impulsion de synchronisation visant à synchroniser certains des premiers temporisateurs et des compteurs de créneaux des seconds dispositifs informatiques pour déclencher le ou les cycles de données. Le système donné à titre d'exemple comprend en outre les seconds dispositifs informatiques destinés à transmettre des données au premier dispositif informatique à l'aide d'un second bus pendant le ou les cycles de données, chacun du ou des cycles de données étant attribué à un dispositif correspondant parmi les seconds dispositifs informatiques.
