Generating timestamps on a packet-oriented bus

Abstract:

An example method is performed on a packet-oriented bus at a point between a source of a data packet and a destination of a data packet. The example method includes detecting a format of the data packet on the packet-oriented bus; determining a time at which the data packet was detected; generating a timestamp report containing the time, with the timestamp report being addressed to a device connected to the packet-oriented bus; and outputting the timestamp report to the device. Detecting, determining, generating, and outputting are performed by digital logic connected to the packet-oriented bus.
