This is my first post ever on a forum, so hopefully, I am as clear as it is needed.
I am using the ZCU104 board with PYNQ to communicate with an ASIC I developed for testing purposes. To do so, I am building my own overlay with Vivado IP integrator and PYNQ libraries. Eventually, the whole system will be used by scientists with no hardware background, so the PYNQ interface seems extremely wells suited.
The chip produces a stream of data transferred to the PL in the ZCU104 through a custom serial interface. An IP block in the PL deserializes the data and then needs to transfer it to an external storage device. The storage device needs to be relatively large to store all the data (i.e. 64 GB or larger). The stream data rate is variable (it is the output of an event-based compression core), but it is never faster than 10 MB/s.
What is the most straightforward way to write from PL to external storage with >64 GB space at >10 MB/s? Should I use the SATA m.2 SSD peripheral, an USB connection to a computer, an ETHERNET connection to a computer, or something else? Ideally, I would like to use a simple IP in the Vivado IP integrator, or an existing example. This seems a common enough situation, so hopefully there is something already out there.
Thanks for any tips you might have. And sorry for the long post, I was trying to be as clear as possible.
