For some perspective on the economic value of improved prediction, you might enjoy reading about a recent, large ($862 million US) patent-infringement award against Apple. Here’s a news article:
And the underlying patent (US5781752):
To me, this says that:
* Improvements to prediction meaningfully improve performance of real CPUs.
* Even incremental improvements in prediction are worth hundreds of millions of dollars!
It will be most interesting to see how the Mill’s prediction (and anti-false-aliasing deferred load) mechanisms work in practice to improve single-thread performance.
