High-precision relative clock synchronization using time stamp counters
Tian, Guosong, Tian, Yu-Chu, & Fidge, Colin J. (2008) High-precision relative clock synchronization using time stamp counters. In Breitman, Karin (Ed.) 13th IEEE International Conference on Engineering of Complex Computer Systems (iceccs 2008), IEEE, Beflast, UK, pp. 69-78.
In this paper we show how to use a computer processor's Time Stamp Counter register to provide a precise and stable time reference, via a high-precision relative clock synchronization protocol. Existing clock synchronization techniques, such as the Network Time Protocol, were designed for wide-area networks with large propagation delays, but the millisecond-scale precision they offer is too coarse for local-area applications such as instrument monitoring systems, high-quality digital audio systems and sensor networks. Our new clock synchronization technique does not require specialized hardware but instead uses the Time Stamp Counter already available in the widely-used Intel Pentium processor. Experimental results show that we can achieve a synchronization precision in the order of 10 microseconds in a small-scale local area network using TSC registers, which is much higher than can be achieved by using a computer processor’s Time-Of-Day clock.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
