An N1-like board to support signal processing and SDR users

Unread post by wittend » Tue Mar 20, 2018 7:13 am

I would like to see a board like the proposed Odroid N1 that directly exposes the PCIe-2 interface for high bandwidth software defined radio (SDR).

Work on bleeding edge data acquisition applications needs a simple Linux platform for human/machine interaction.

Designers often want to avoid the unpredictability of USB3 (though don't eliminate USB3). But they need a couple of lanes of fast I/O.

I use an Odroid C2 to connect 4 SDRs remotely via ethernet with a powered USB hub and it works well.
The RTL-SDR and RSP2 recommend USB 2.0 ports which is why I didn't get an XU4 and the extra CPU oomph. In the future, I can see most SDRs using USB 3.0 and mini-PCIe for the bandwidth and latency respectively.

Another thing of note is that SDRs connected to hardkernel boards could utilize well is high quality DACs - sampling rates in excess of 384 kHz may not be essential for human hearing, but SDRs can make amazing use of them. I was pleased to see the N2 having a high quality DAC.
