I have a question regarding the Ethernet IP Core specification datasheet by Mr. Igor Mohor.

The core has two Wishbone interfaces : SLAVE and MASTER bus interfaces.
As far as I understand, in order to send a data frame, a Buffer Descriptor (BD) should be
associated with the data. My question is:

How do I associate this BD with my data frame in memory? How do I access its address?

Do I use the wishbone SLAVE interface or rather the MASTER interface bus?

I am asking this because as I understand, the WISHBONE MASTER interface doesn't have an ADDRESS OUT lines in it.

Thanks,

Abe

The wishbone master interface has address out pins. They are called m_wb_adr_o
