Best way to do real time data transferring

I am working on a design where I will need to transfer 32 words from a Microblaze to a Block Memory  and 32 words from a block memory to the same Microblaze every 62.5us as part of a real time system. I am looking for ways to do this with the least amount of overhead to the Microblaze.


I have been looking at the AXI4 Stream FIFO and was wondering if this was the recommended solution (or is there a different recommendation?). If so, what is the easiest way to connect this to a Microblaze on one side and some sort of engine to load/unload the block memories on the other?


Also what is the overhead difference for the Microblaze on using the AXI Block memory vs the AXI Stream?


All comments are much appreciated.
