Abstract

A method includes executing a branch instruction and determining if a branch is taken. The method further includes evaluating a number of instructions associated with the branch instruction. Upon determining that the branch is taken, the method includes selectively writing an entry into a branch target buffer that corresponds to the taken branch responsive to determining that the number of instructions is less than a threshold.
