TMS320C6452 DDR Controller

Other Parts Discussed in Thread: TMS320C6452

Can anyone tell me how difficult it would be to interface a TMS320C6452 and two DDR SDRAM IC's with a microcontroller? The goal is to increase the memory for a microcontroller while at the same time use the processing power of the TMS320C6452 core. Would I need to use eDMA? Is it feasible to add a connector to the MCU and have the TMS320C6452 + DDR SDRAM on a external  pcb?

Thanks in advanced for any ideas.

    What microcontroller is it?  What's the fastest available interface on your specific microcontroller?  Why did you choose C6452?  I would suggest something a little newer such as c6748.  This is the first time I've ever heard of anyone doing this sort of thing.  Sounds plausible, though a fair amount of work.  The power supply design will be much harder for the DSP than for your microcontroller.  Plus you'll need non-volatile memory to boot the DSP and the DDR2 layout will probably take more effort than anything on the microcontroller.  But all that aside, yes, it is certainly feasible.
