High bandwidth data transfer between hps and fpga

Hi, I need to High bandwidth data transfer between hps and fpga. Which bridge should i use? I used light weight bridge but the speed of transfer data was up to 3MHz. Best Regards

Hello,

we have implemented "High-Bandwidth" data transfer using the sdram to Ethernet-method with Cyclone V SoC. The data flow is data(fpga)->sdram->HPS EMAC -> TCP/IP -> Host PC. We get about 200 Mbit/s throughput with this method. The bottleneck of this method is the Sdram-controller's maximum clock speed which is 300-367 MHz (dependig on the device's speed grade). So this method would maybe not work for you if want to get at least 480 Mbit/s throughput.

Thanks for reminding. It seems like my flow currently, but I wanna give it a try. :confused:

How do you configure the flow from sdram to TCP/IP? Where can I configure the IP address, port for socket? Could you share some ideas to implement it?
