really great article. love it, super clear and consise. This kind of mechanisms are super interesting to learn more about. I'm curious to the new AMD cpus which use neural network to predict branches, how that fits into the performance and what kind of accuracy it peaks at.
- ovi256 7y agoA brief introduction can be found in this post here: https://chasethedevil.github.io/post/the_neural_network_in_your_cpu/ https://chasethedevil.github.io/post/the_neural_network_in_y... It talks about “Dynamic Branch Prediction with Perceptrons” (Jimenez 2001) which sparked the whole thing. The AMD engineers read this paper (and probably many more!), put together a development program, and shipped it.
