[How to use and manage memory with my FPGA?]

Whether you are timing a photonic sensor or a button, you will be doing asynchronous sampling at some appropriate clock rate that is unrelated to your DUT (device under test).

I thought of implementing synchronous sampling since I thought that asynchronous sampling is slower and not fast enough for my project.
I am now trying to learn how to save to memory.
also apologies for the poor explanation of my problem, I just never used FPGAs before and never learned verilog or any other HDL language such as VHDL

[How to use and manage memory with my FPGA?]

Hi, I have a goal of building a cheap CCU (coincidence counting unit) using my xc7s25csga255-1 spartan 7 (link).

I want to be able to record all the pulses and save them (using a photon detector device that will connect to the FPGA).

To start with something simpler, I want to record how many times I press a button and measure the time between each click.

When I'm done, all the data that I recorded should move to an external computer.

How can I achieve this?
 

edit: I need to implement a CCU (coincidence counting unit) using my xc7s25csga255-1 spartan 7 (link). I'm using Verilog and working with Vivado.
I want to be able to record all the pulses (using a photon detector device that will connect to the FPGA) from 2 channels and if both of them are active at the same time, record that (I think using an and gate) and also save when it happened. I want all the data that was recorded to be transferred to a computer (it can happen during the experiment or after it). I thought of using UART to send data but to my understanding, it's not fast enough.
The whole operation should take about 30 seconds.
I might be wrong but I think that in order to achieve this, I need to first write to BRAM as I run the experiment, and then transfer the data to a computer (I think that writing to BRAM is faster than transforming the data to a computer I might be wrong).
