DDR access from both a custom peripheral and a MicroBlaze?

Hi,

I'm designing a system that requires my custom peripheral to receive commands and data from a MicroBlaze using a FIFO-like buffer.  As such, it seems to me that the best choice for this would be to use an FSL connection.  However, this peripheral also will need to be able to read from and write to the DDR memory used by the MicroBlaze.  What would the best approach be for doing this?  Am I able to just use the MIG within my peripheral, or will there be conflicts with my peripheral and the MicroBlaze trying to use the memory device at the same time?  

Thanks!
Eric
