Development of Embedded Simple Network Time Protocol Client Clock

Abstract

This paper describes the development of an embedded SNTP clock which applies NTP Protocol to embedded clock to realize the high accuracy and precision SNTP client clock. It consists of three parts which are the communication part to communicate between NTP Server and SNTP client clock, the data processing part to process data packet, and maintain accuracy, precision of time, and the result displaying part to show time together with the reliability status of the clock. This article explains the concept of applying and analyzing NTP packet, process of maintaining accuracy and precision of time and displaying the result, and hardware, software designs. This paper will provide the introduction of NTP, the development of NTP on the embedded clock, the simulation, and results of the experiment.
