ABSTRACT:
In a method for predicting whether a branch will be taken when a computational circuit executes a conditional branch instruction, a branch prediction field is associated with the conditional branch instruction. The branch prediction field includes at least a first state and a different second state. Upon accessing the conditional branch instruction, if the branch prediction field is in the first state the conditional branch instruction is prepared to execute as though the branch will result. If the branch prediction field is in the second state, the conditional branch instruction is prepared to execute as though the branch will not result.
