MicroBlaze and MPMC with different frequencies (Being asynchronous)

 

Hello,

 

Is there possible to have a system that in which MicroBlaze (MB) processors and memory controller(MPMC) work with different frequncies (Except 1:1 or 1:2 clock ratio between MB and MPMC)? 

I work on a virtex-5 FPGA (xc5vlx50t).

 

Thank you in advance.

There is no requirement that they be on the same or synchronous frequency. You generate the IPs separately and you can connect them anyway you like; as long as you make sure the data is communicated between the components correctly (ie asynchronous FIFOs or asynchronous AXI interconnect etc) you are fine. You can connect any clock to either IP.
