how do I connect external RAM to it, and what would be the cpu-to-memory bandwidth in that case

External RAM, up to 1 Petabyte would be connected through an external FPGA, containing an epiphany link, some glue logic, and a memory controller.

thanks, Andreas. is there an existing solution, or is it DIY project at this point?

From my understanding the Zynq's memory controller can only handle ~4GB of memory. Am I missing something? Is there a way to connect more than 4GB -- if so, I'd be very interested.

Larger FPGA support 64-bits with custom memory controllers.

With the new chip, is there a memory controller on the board, or will you still need the FPGA's?

Even with the new MPSoC, I think the memory controller is limited to 8GB.

Do you know what the most efficient cost / GB confit is for a Epiphany + memory controller or FPGA
