mkPriorityFlowControlTx负责报文发送端的PFC控制,其接收八路发送数据流dataStreamInVec和八路报头信息流udpIpMetaDataInVec,对这两组八路数据流进行仲裁后分别通过udpIpMetaDataOut和dataStreamOut接口输出仲裁结果。仲裁采用Round Robin策略,给予八个通道相同的优先级。同时,该模块还负责根据PFC报文中提供的流控信息flowContro...

由于rx_mac_aclk是由rgmii_rxc得到,和tx_mac_aclk是同频率但是相位不同,这里将其缓存在fifo中作跨时钟域处理。 proc_sys_reset 由于rx_reset和tx_reset都是高有效,利用系统复位IP生成同步低有效复位给后续IP使用。 9 数据接口时序 Receive 正常情况下,AXIS接收时序如下所示: ...

CPDMA RX and TX 接口 CPDMA 子模块是cppi3.0协议的dma packets传输控制器,他是port0。主控写 STATERAM块里面的 发送通道头描述符指针地址 来初始化发送操作。这样发送dma控制器会从packet链里面取出packet发送到外部的发送fifo里面去,64字节最大一次。

The auto-negotiation function also allows the interfaces to negotiate about the flow control function. If a local interface works in auto-negotiation mode and the remote interface works in a non-auto-negotiation mode, the negotiated working mode of the local interface depends on the working mode ...
