    • A synchronization module for providing synchronization messages to be sent with a time stamp in accordance with the PTP protocol of standard IEEE 1588 is provided. The synchronization module comprises a program module for generating a synchronization message to be sent and for providing the synchronization message with a first time stamp, and a hardware-implemented time stamp module which receives synchronization messages from the program module and forwards them in accordance with the PTP protocol. The time stamp module comprises a real time clock, a message detector for recognizing a synchronization message by its difference in relation to other messages and a message manipulator for overwriting the first time stamp in a synchronization message recognized by the message detector with a second time stamp actually retrieved from the real time clock.
    • 提供了一种同步模块,用于根据标准IEEE 1588的PTP协议提供要与时间戳一起发送的同步消息。 同步模块包括用于生成要发送的同步消息和用于提供具有第一时间戳的同步消息的程序模块,以及硬件实现的时间戳模块,其从程序模块接收同步消息并根据 PTP协议 时间戳模块包括实时时钟,消息检测器,用于通过与其他消息相关的差异来识别同步消息,以及消息操纵器,用于在由消息检测器识别的同步消息中用第二时间戳覆盖第一时间戳 实际上从实时时钟检索。
