Simple solution for external memory writes on CycloneIII sterter board.

Hello,

Altera has DDR controler IP available.

For your purposes, I believe the easiest way would to make your processed data available with an Avalon interface.

Can be either an Avalon-MM slave or a or Avalon-ST source. At your rates, it hardly matters.

You can then build a SOPC with

a) your component

b) a DDR controler component

c) a NIOS II processor component

d) JTAG-UART component to handle the data transfer

"b)" to "c)" are readily available for you in the SOPC builder.

You can then write a small program (in C) for NIOS to read processed data from your component and store it in DRAM and to comunicate with the PC over USB-Blaster.
