I’m testing single board computers and wearing out SD card by constantly flashing them with different builds, not to mention it tiring to keep swapping cards in & out. So => emulate and SD card and “store” the data on a host pc connected via USB.

Diagram:

microSD interface <— FPGA —> USB <——> Host computer with SSD storage

I will be using the SD 4-bit interface and would like to hit transfer speeds > 50MB/s, the clock should be ~100Mhz (UHS-I Ultra High Speed support including 104Mbyte/sec (SDR104) and Double Data Rate (DDR50)).

From Xilinx site : this IP seems to do exactly that and supports the Zynq-7000

is this possible with the Zynq on board the parallella?
