【摘要】 以高级夹层卡——AMC(Advanced Mezzanine Card)以太网交换板的实际设计为例,详细介绍基于MicroTCA系统的AMC板的实现技术。AMC以太网交换板按功能可划分为以太网数据交换和管理控制模块(Module Management Controller,MMC)两部分。本文从芯片选型、逻辑功能、互连总线、管理接口等方面对这两部分的功能实现进行了描述,尤其是对MMC管理功能模块的软硬件实现技术进行着重说明,为NMicroTCA系统中其它类型的AMC板的开发提供参考。更多还原

【Abstract】 This article takes the design of the AMC( Advanced Mezzanine Card) Ethernet switch board as an example to introduce the realization of the AMC board based on the MicroTCA system. The AMC Ethernet switch board can be divided into two logical parts: Ethernet switch module and Module Management Controller( MMC). This article introduces the chip selection, logic function,interconnect fabric,and management interface of the two parts. Most of all,it gives a full description of the design of the Module Management Controller( MMC) on the AMC board,which provides a good reference of designing other types of MicroTCA AMC boards.更多还原
