Honored ContributorHi Manos:
I would look at the SoCKit from Terasic for a project like this versus the DE0. It has dual Arm Cortex A9 cores running upto 800 MHz, plus a HSMC connector for attaching the ADCs. Terasic doesn't have a HSMC adc board running at 250 Msps, but they do have some 14 bit adc boards running 150 Msps. If you have a specific ADC you are looking at, see if they have a dev board that attaches to an HSMC connector. I know many of the ADC vendors either have it already or they have a HSMC to their board adapters already. Can you do this with Nios? Yes, but it will not run as fast as the ARM. Can you draw everything fast enough? Not at 250 Msps. But at some reduced rate yes. The SOCKit gives you 2GB of DDR 3 to play with. So you can do a lot with it. Start playing with QSYS. Most likely you will have to write at least some of the hardware yourself to get it all to play nice... The ADC to memory interface is what probably will not be there for you. You should be able to use QSYS to get the basic system up and running, and add on all the basic IP cores required for the SOC portion. But you will have to write the ADC interface, and make it compatible with the standard DMA controller. Writing samples at 250 Msps is not trivial, so it will take some work. Pete
