What is the best way to transfer data from FPGA to HPS at 40 MHz rate?
I want to transfer data coming out from ADC connected to FPGA to the HPS. Later, I want to transfer it from HPS to a host computer through Ethernet. My question is what is the best SoC design that fit my requirements?
* Writing to SDRAM memory using Modular Scatter-Gather DMA? or * FIFO with light-weight bridge and continues polling in my application running in the HPS? I have tried writing to SDRAM memory, but I'm having difficulties in working with memory descriptors ...:( I would really appreciate any help :) Thank you very much in advance!
