xxv_ethernet_0_mdio: mdio { #address-cells = <1>; #size-cells = <0>; }; }; When Soft Ethernet MAC configured with MCDMA, The driver supports several features of the MCDMA- The driver supports random Queue/Channel selection. Assume in vivado design MCDMA is configured for 16 channel...
与读出通道对应,AXI MCDMA会向BRAM_CTL_1写入测试数据,检查数据正确性的时候,测试逻辑是直接检查的写入信号,并不是将BRAM 1中写入的数据读出做校验,这一点需要查看仿真波形,有可能设计人员偷懒,所以这样写的 descriptor信息预先存储在BRAM_CTL_3中,由AXI MCDMA的AXI SG接口将对应的信息读出,对应的descripto信息存...

* 上述任何 IP 核的硬件评估许可证都将帮助您在您的设计中生成这些内核,并对其进行参数化和实例化。此外,您还能够执行功能及时序仿真,并生成一个您可用于下载和配置您的硬件设计的比特流。 该表中的 IP 核将在编程的器件中全面工作一段时间。这段时间之后,IP 将“超时”(停止工作),您需要再次下载并配置 FPGA...
75218 - 2020.1 Zynq UltraScale+ MPSoC: AXI Ethernet driver in specific MCDMA configuration throws swiotlb full error with jumbo frames Description In my ZCU102 design which includes 10G and MCDMA (32-bit), I am seeing a swiotlb buffer full error when the MTU is set to 9000. ...
若想让ZYNQ的PS与PL两部分高速数据传输,需要利用PS的HP(高性能)接口通过AXI_DMA完成数据搬移,这正符合PG021 AXI DMA v7.1 LogiCORE IP Product Guide中介绍的AXI DMA的应用场景:The AXI DMA provides high-speed data movement between system memory and an AXI4-Stream-based target IP such as AXI Ethernet...
