摘要
PCIE(Peripheral Component Interconnect Express,PCIE)交换芯片是一种应用于PCIE设备互连的交换设备,每个端口均支持PCIE全协议栈。PCIE交换芯片主要由物理层接口模块、端口控制器模块、路由模块、EEPROM接口控制器模块、配置模块和交换核心模块组成,该方法能实现PCIE协议定义的PCIE交换功能,能对交换机的各个端口寄存器进行配置,实时在各个端口之间线速转发PCIE事务层报文(Transaction Layer Packet,TLP)。虽然市场上有不少PCIE交换芯片,但目前很难找到的PCIE交换芯片实现的设计方法,本文提供了一种PCIE交换芯片的数据交换管控实现方法,能实现PCIE协议定义的PCIE交换功能,实时在各个端口之间线速转发PCIE TLP。
The PCIE switch is a kind of switching device which is applied to the interconnection of PCIE devices.Each port supports the PCIE full protocol stack.The PCIE switch chip is mainly composed of physical layer interface,port controller,route,eeprom interface controller,configuration and switch-core module,which can realize the PCIE switch function defined by the PCIE protocol,can configure the various port registers of the switch,and forward the PCIE TLP in real time between ports.This paper provides a PCIE switch chip data exchange control implementation method,can realize the PCIE protocol definition of PCIE switch function,real-time transmission of PCIE TLP between ports at full speed.
