基于POWERPC架构的多网口嵌入式通信控制终端的以太网设计
esign of Ethernet Module on Embedded Communication Terminal Based on PowerPC
PowerPC处理器在目前的嵌入式通信领域内有不可取代的优势，本文基于Freescale公司QorIQ平台的P2020E处理器设计多网口嵌入式通信控制终端系统的以太网模块，为系统实现数据汇聚、交换等功能。本文阐述了系统的设计框图及模块搭建方案，其中详细阐述了以太网模块的基本设计原理，基于SGMIIRGMII等接口对应不同型号以太网PHY的硬件设计，以及以太网模块的抗干扰设计等网络模块的关键设计问题。经测试本系统能可靠的工作，完成数据交换、存储等功能。
Embedded system, based on PowerPC, has an irreplaceable advantage in communication field. The paper designs an embedded multi-port network terminal stystem based on P2020E which made by Freescale QorIQ communication platform, and has the function of network data exchange and aggregation. This paper shows the system block diagram and module scheme. Especially, it explains the key issue in embedded network design such as the fundamental rules in etherent design, hardware design of different ethernet PHY based on SGMII/RGMII and anti-interference design in ethernet module. The system, which has been tested, can reliably work and complete the network communication function.
