20150277910 | METHOD AND APPARATUS FOR EXECUTING INSTRUCTIONS USING A PREDICATE REGISTER - An apparatus and method are described for executing instructions using a predicate register. For example, one embodiment of a processor comprises: a register set including a predicate register to store a set of predicate condition bits, the predicate condition bits specifying whether results of a particular predicated instruction sequence are to be retained or discarded; and predicate execution logic to execute a first predicate instruction to indicate a start of a new predicated instruction sequence by copying a condition value from a processor control register in the register set to the predicate register. In a further embodiment, the predicate condition bits in the predicate register are to be shifted in response to the first predicate instruction to free space within the predicate register for the new condition value associated with the new predicated instruction sequence. | 10-01-2015 |
