hps emac route to FPGA fabric(use Cyclone V SX-5CSXFC6C6U23C7)

Hi ,

I now directly control the function of emac through hps.

So the external PHY is directly connected to the I/O pin of hps, as shown in figure.

 However, the speed of the ethernet is limited to less than 100Mbps due to the large image data to be transmitted.

    So I want to replace the function of image transmission through FPGA(and keep ethernet command control in hps), as shown in the figure below.

 And the question I want to ask is:

1.Is there any way to allow FPGA to control the I/O of HPS without changing the PCB layout?

2.If this method can be achieved, will his speed be limited?

 

Thank you.

Hi,


Yes you can route to FPGA, though the speed limitation is always be affected and varied by designs itself.

Hi,


Do you have further questions?
