  • Driver for network timing systems
    Patent number: 10762013
    Abstract: Devices and methods of providing drivers for software and hardware systems to avoid additional polling or interrupt mechanisms are provided. An electronic device includes a processor supporting a device driver to perform a data packet receiving operation or data packet transmission operation. The device driver causes the processor to receive one or more data packets to a port of the processor according to a time-synchronization protocol. The device driver polls the DMA feature for a completion status of the storing. The device driver causes the processor to determine a timestamp of the one or more data packets and to complete the data packet receiving operation without the device driver causing the processor to perform a polling operation or an interrupt operation to retrieve the timestamp of the one or more data packets.
    Type: Grant
