Max sample rate?

[fpgasdr]

Hello, congratulation for the amazing work it looks amazing.

I'm just curious about this because is picture of max transfer with iperf3 you get more or less 95Mbits but it is because the ethernet is configured as 100mbps but the ethernet chip could handle 1gbps.

Also from other pluto-like board with ethernet they stated the bottleneck is in the iio driver but 10Msps could be achieved and from analog specification(2 bytes per sample and IQ baseband) this is about 320mbps. Also the pluto board could get 24MBps with usb2 because usb bottleneck.

it's possible to get gigabit ethernet or is still in progress?.

Thanks, juli.

Hello, thank you very much for your interest in my project. At present, the development of eth for this project has been completed. Theoretically, it can reach a sampling rate of 19msps (occupying about 700-800mbps bandwidth, please use gigabit link equipment). This project uses rtl8211e to automatically negotiate as a 1000m Ethernet in the system. The relevant firmware has been released [https://github.com/kangyuzhe666/ZYNQ7010-7020_AD9363/releases] At present, we are further improving the stability of the hardware, and a stable hardware version will be launched in March. At that time, the price of the hardware will be much lower than the same pluto hardware with eth on the market.

Thanks, yuzhe Kang

Thanks and please let me know if you get to capture with this throughput 800mbps, no much sdr board can do this, but as far I can understand form the pluto+ creator who just import the pluto firmware to its board(and he uses the same rtl8211 chip):

"At present, when the test reaches 10M bandwidth, it will be stuck, which is far from full of Ethernet bandwidth. We analyzed the reason is that ADI's IIO drive efficiency is too low, and time is spent on memory copying."

Hello, thank you very much for your reply. I am not sure about this developer's firmware development on Twitter. ZYNQ7000 has two ARM A9 cores. It can only be limited to about 10M when using one core. The official firmware of pluto only turns on one core by default. Our project uses two A9 cores, so it can meet the sampling rate above 10M, please continue to pay attention to my github dynamics. We will upload more test data in the future. Since I am currently on holiday, I cannot provide too much data to you. Please wait for a while.

Thanks for your attention.I will stay on tune.

hello! Can you please tell me, when using this together with the ZYNQ7020, will it allow me to get 61.44msps on ETH?
