摘要

目前关于并行帧同步方案的研究大多是针对某种具体应用的

结论缺乏一般性.同时一些新出现的帧同步问题(如10G以太网中66B码的帧同步)具有一些新特点.本文提出了一种新的并行帧同步系统构成模式MCSCI

它采用连续性判别的方法进行同步码位搜索.当将MCSCI用于66B码帧同步时

和现有模式相比以较小的面积开销获得了最佳性能.本文在理论分析和计算机仿真的基础上

研究了一系列典型参数下新旧并行帧同步系统的性能

结果表明MCSCI具有广泛的应用前景.

Abstract

Present researches of parallel frame synchronization schemes are mostly focused on one or another special application

and the conclusions lack general significance.Some new frame synchronization problems-such as 66B code synchronization in 10 gigabit ethernet-have their new characteristics.This paper proposes a new parallel frame synchronization scheme

namely MCSCI

which uses a method featured by continuity validation to perform searching of frame alignment word.When MCSCI is used in 66B code synchronization

optimal performance is acquired at the expense of smaller chip-area

compared with present schemes.Based on theoretical analysis and computer simulations

this paper studies the performances of proposed and present schemes under many suits of parameters

and the results show that MCSCI has broad usage.
