interfacing with PC is done commonly through nios. If you want a short cut then use realtime editable rams and update them with your new file. for that you need to instantiate rams and activate the realtime edit feature.
for adding values of distance use accumulator(just feedback register). for each sum first clear it then sum up in the feedback loop till some 2^n samples so that at the end you truncate n LSBs and clear it for next update.
