  Hardware Assisted IEEE 1588 IP Core

  

Interesting project, especially to gain insights into the FPGA programming part.

I think it is essentially a mixture of PTP and NTP now.

I guess this will work within the same local network, as the major inaccuracy of NTP comes from the asymmetric path delays at the network layer over the Internet.

PTP solves this by incorporating these hardware timestamps exactly. But this works only within the same LAN.

Here is an interesting PTP core:

Yes it is "old" but that is typically fine with HW projects.

You might find this repo interesting.

I have a 500 MHz oscilloscope on hand so I can decently measure the offset between the raspberry pi PPS and GPS PPS.
