    摘要: A method and system in a data processing system of permitting concurrent processing of multiple conditional branch instructions are disclosed. A condition register is established within the processing system. First and second conditional branch instructions are dispatched during a single cycle of the processing system. Prior to speculatively executing the first conditional branch instruction, a first copy of the condition register is stored. Prior to speculatively executing the second conditional branch instruction, a second copy of the condition register is stored. Multiple copies of the condition register are concurrently maintained so that the first and second conditional branch instructions may be concurrently processed during a single cycle of the processing system.
