Static Branch Prediction

Static branch prediction is a branch prediction strategy in which the prediction is fixed and does not depend on the execution history of the branch.

Schemes

Always not taken

Always not taken

Always predict that the branch is not taken, so execution continues with the next sequential instruction. This is sometimes called fall-through prediction, because the processor stays on the path $PC=PC+4$.

Always taken

Always taken

Always predict that the branch is taken, so execution jumps to the branch target.
