hello,
im a total newb, so please be a little bit patient with me;
im looking for a way to handle by means of a microcontroller a rather big amount of dram; most devices i found so far only do up to 2 or 4 gigs or ram and i definitely need more, im aiming for 16 gb; the memory itself will hold only data, its meant to be a buffer; the speed range, depending on the final interface, from 40-60 to over 200 mb/s (memory bandwidth); could anyone suggest how i can attain such an amount of memory on any 32bit microcontroller? or are there 64bit device on the market with a more or less normal price tag? if not a device, with an integrated dram controller, maybe an external controller attached to a 32 bit controller could do more memory? but would it perform attached via gpio or whatever? or is this a task for a fpga to simulate a wider adressable range?
thanks
