What are some examples of branch prediction techniques?

Branch prediction techniques are methods used in computer architecture to improve the flow of instruction execution. Some examples include static prediction, dynamic prediction, and two-level adaptive prediction.

Can you explain static prediction?

Static prediction is a technique where the compiler makes predictions about branch behavior at compile time, often based on heuristics.

What about dynamic prediction?

Dynamic prediction uses runtime information to make predictions about branches, adapting to the actual behavior of the program as it runs.

How does two-level adaptive prediction work?

Two-level adaptive prediction uses two levels of history to make predictions, tracking both global and local branch history to improve accuracy.
