General Description |
Hardware Assisted IEEE 1588 IP Core. The necessary FPGA logic to assist SW protocol stack in implementing the Precision Time Protocol (IEEE 1588-2008) on 1000M/100M/10M Ethernet networks. PTP packet transmitting and receiving is implemented by PTP SW protocol stack with any existing MAC function internal or external to the FPGA; The IP Core implements the Real-Time Clock (RTC) and Time Stamping of PTP event packets (TSU). |

Hardware Assisted IEEE 1588 IP Core. The necessary FPGA logic to assist SW protocol stack in implementing the Precision Time Protocol (IEEE 1588-2008) on 1000M/100M/10M Ethernet networks. PTP packet transmitting and receiving is implemented with any existing MAC inside or outside the FPAG; The IP Core will implement the tunable Real-Time Clock and Time Stamping of PTP event packets (L2, UDP/IPv4/MPLS/VLAN and UDP/IPv6/MPLS/VLAN) in two-step-mode. |

The IP Core can be used as an IP Component in Altera SOPC Builder. |
PCAP file based stimulus input is used for verification with real-world traffic. |
|
The only FPGA vendor dependent module is the timestamp queue. This Altera DCFIFO can be replaced by other FPGA vendor specific dual clock FIFO. |
