Systems and methods of processing branch instructions provide for a bimodal predictor and a plurality of global predictors. The bimodal predictor is coupled to a prediction selector, where the bimodal predictor generates a bimodal prediction for branch instructions. The plurality of global predictors is coupled to the prediction selector, where each global predictor generates a corresponding global prediction for a branch instruction using different history or stew lengths. The prediction selector selects branch predictions from the bimodal prediction and the global predictions in order to arbitrate between predictors. The arbitration, update, and allocation schemes are designed to choose the most accurate predictor for each branch. Lower level predictors are used as filters to increase effective predictor capacity. Allocate and update schemes minimize aliasing between predictors.

A method of one aspect may include receiving a rotate instruction. The rotate instruction may indicate a source operand and a rotate amount. A result may be stored in a destination operand indicated by the rotate instruction. The result may have the source operand rotated by the rotate amount. Execution of the rotate instruction may complete without reading a carry flag.

A method in one aspect may include receiving a multiply instruction. The multiply instruction may indicate a first source operand and a second source operand. A product of the first and second source operands may be stored in one or more destination operands indicated by the multiply instruction. Execution of the multiply instruction may complete without writing a carry flag. Other methods are also disclosed, as are apparatus, systems, and instructions on machine-readable medium.
