摘要

在光传送网中

ODUk（光通路数据单元k

k=0

2）分组模块的主要功能是将ODUk切割为格式固定、标准包大小为±1字节的数据包。由于ODU2是8字节的数据

每次插入数据包后剩余的数据字节数不同。文章研究了ODU2切割数据包的过程中剩余数据处理的实现方法与电路设计

并进行了功能仿真和逻辑综合。结果表明

该方法减少了资源占用量

可以将电路的工作频率提高到360MHz。

Abstract

In Optical Transport Networks（OTN）

the main function of the Optical Channel Data Unit（ODUk

k=0

2）segmentation module is to cut ODUkinto a standard sized packets（±1byte）in a fixed format.As ODU2 is 8-byte data

the number of the remaining data bytes is different after each insertion into the packet.This paper studies the implementation method and circuit design for the remaining data processing in the above process and completes functional simulation and logic synthesis.The results show that this method reduces the resource occupation ratio and increases the circuit operating frequency to 360 MHz.
