Can we loop and avoid cache misses for computer performance?

If you iterate over data, the most efficient retrieval is where the data is all in a line.
How do we arrange data so that data is always near the previous data we retrieved?

I wrote a nested for loop that iterates in reverse order between iterations to minimize cache misses.
私はこれに数時間を費やしました。
これをプログラムのすべてのループに適用すると、さらに効率的なプログラムを作成できます。

I spent a few hours on this.
If this was applied to all looping of programs, we could have even more efficient programs.
