Hi Martin,
Yes you're right, 75000 items isn't so large! But after passing these items through an encoder, the number of items becomes about 227000!! That's a big number!
However, I skewed over the problem and till now I've reached to this point that I may use 3 or 4 inputs-ouputs ports per block (instead of actually one input-ouput port) and divide the 227000 items into 4 parallel streams and read all of them through 3/4 different input ports and put them out to the 3/4 output ports ! That seems work but I'm not sure that's the best one.
If you have any idea I'll be appreciate you so much.
best,
