FPGA_NTP_SERVER

Introduction

This repository contains the source code for a complete, FPGA based hardware implementation of a Network Time Protocol (NTP) server. The implementation includes hardware support for Network Time security (NTS).

The server implements the complete network stack in hardware, which allows high performance, low latency and low jiter. The design supports scalability through parallel, independent network engines.

The repository contains setup and build targets to implement the server on existing FPPGA boards. The currently supported FPGA boards ar:

Look at README.md in the respective target directories for more information on how to build an FPGA image and for the two FPGA reference boards. The VC709 project has the most complete instructions on how to use it, the VCU118 project lacks documentation on how to set up the hardware, but is is fairly similar.

Status

The design is complete, verified and tested in real hardware and systems. The server is used to operate the Swedish Distributed Time Service.
