1. A method for predicting whether a branch will be taken when a computational circuit executes a conditional branch instruction, comprising the steps of; a. associating a branch prediction field with the conditional branch instruction, the branch prediction field including at least a first state and a different second state; and b. upon accessing the conditional branch instruction, preparing to execute the conditional branch instruction as though the branch will result if the branch prediction field is in the first state and preparing to execute the conditional branch instruction as though the branch will not result if the branch prediction field is in the second state, thereby generating a branch prediction.
