| Hi 
Igor,   Can 
you tell me when the host interface that doesn't use DMA will be 
completed?  Do you have any preliminary information on it?  We are 
planning to implement the ethernet core into our ASIC, and the non-DMA interface 
will work much better for us.  We will be implementing an FPGA version in 
about six weeks and then the ASIC after that.     Also, 
do you have any timing diagrams that could be added to the ethernet core 
documentation?  That would be very helpful!   Thanks!   Donna     
  
  Hi,   1. 
  The source address is built from 48 bits like: 01-02-03-04-05-06. You can get 
  the first 24 bits from the ieee organisation. The other 24 
  bits are up to you. You can use serial number of the board or something like 
  that.   2. 
  It is up to the host to set the destination address and not up to MAC. From 
  the MAC's point of view the destination address is just part of the packet to 
  send. Host can use anything for the destination address.   3. 
  Yes. And that source must add the destination and source address to the data. 
  I'm writing a host interface that won't use DMA but normal wishbone 
  cycles to get/store the data.   Regards,     Igor |
