RE: [ethmac] fifo reset

Hi,

 

as far as I know there is no such thing in Xilinx that only read side of the fifo can be reset (only both). However you

can use the dual port ram and build the fifo yourself. Read side can then be reset easily.

Subject: [ethmac] fifo reset

Hi,
  In my design ,Fifo is used to store the frame data that is to be transmitted.When col occurs during transfer,
the frame will be re-transmitted.I want to reset the read point(read address) only when col occurs.Then it is not
neccessary to transfer data from memory to fifo.But i can not find any core in xilinx that provides the function to
reset read point.Who can give me a suggestion on how to reset the read point? Or any better methods ?
Thanks.
