Xilinx V7 Series FPGA-developed TCPIP IP Core Characteristics: 1. Support for multiple 10G Macs 2. Each TCP hard-core stack supports 8 logical interfaces. Each interface can have a unique IP, physical address, VLAN ID, gateway, subnet mask. 3. Support for 9K bytes of extra long package 4. Support VLANs 5. Embedded ARP 6. Connect the 10G pma-pcs PHY with the Xgmii high-speed interface 7. A axi4-stream interface that works in 156.25MHz 64bit allows users to debug and use 8. The IP core can be configured via a 32bit axi4-lite slave protocol 9. User interface for 128bit axi4-stream working in 156.25MHz 10. TCP session mode for up to 128 concurrent clients or servers. Each session can be connected to any logical interface 11. Turn on specific flow control features for each session 12. User-Configurable TCP options: MSS, timestamp, VLAN PCP, VLAN DEI 13. If the packet length is greater than the value from the user application interface remote configuration (MSS), the load is automatically split. 14. Configurable TCP re-operation Memory: width, depth, internal or external This design scheme supports two modes of hardware board sales and IP sales. You can also delegate the design of the finished product. In addition to supporting the VIRTEX7 series, IP can also support the development of higher-grade chips such as the UltraScale series.
