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.
