Course Handouts and General Information:
Background on branch prediction:
This describes, among other things, the use of adaptive/dynamic state machines (e.g. saturating counters) to track branch behavior and to predict future behavior based on that observed past behavior.
A nice description of the branch-target buffer and a description of what Yeh & Patt call a "static training" branch prediction scheme in which a branch history (string of bits signifying taken/not-taken status of most recent branch outcomes) is used to generate a prediction. That prediction can be generated by profiling a set of benchmarks. The article also explores a few other adaptive state machines besides saturating counters.
By the way, the article is huge, weighing in at 16MB. Here is a 3MB file, with a bit of a image-quality tradeoff (I photocopied it from the original).
Combines the concept of the history-indexed table, as described in Lee & Smith  (called static training by Yeh & Patt) and the use of adaptive state machines, as described in Smith . Instead of putting a static prediction bit into the table, an adaptive state machine is put into each entry in the table. Note that later papers by Yeh & Patt change the name of the scheme to "two-level adaptive branch prediction" (dropping the "training").
