 Primarily we fetch data when you request it. If you've requested data, it's obviously needed immediately. We have a limited amount of bandwidth, so we usually don't want to do a whole lot of speculative loads. But we could. We can consider that if you're listening to some music or watching a movie, you're walking down this really, really large array. And it's really easy to see that you're walking down a really, really, really large array and figure out that maybe I should go fetch this data before you need it. This is often done in software where we can clearly say, oh yes, I know I'm watching a movie. I'm playing it back. I'm going to buffer this data ahead of time. I will go crab it from wherever it's at and stick it as close to the processor as I can so that when we actually need it, it's ready to go.
