The Low Latency E-Tile 40G Ethernet hardware design example includes the following components:

  • Low Latency E-Tile 40G Ethernet Intel® FPGA IP core.
  • Client logic that coordinates the programming of the IP core, and packet generation and checking.
  • IOPLL to generate a 100 MHz clock from a 50 MHz input clock to the hardware design example.
  • JTAG controller that communicates with the Intel® System Console. You communicate with the client logic through the System Console.
