PROBLEM TO BE SOLVED: To provide a method for processing interruption and branching recovery unrelated to the type of generated interruption by dispatching an instruction and source information to an execution queue, judging the propriety of the source information and issuing the instruction for execution in response to the propriety of the source information. SOLUTION: This method is provided with a step for dispatching the instruction and the source information to the execution queue, the step for judging the propriety of the source information and the step for issuing the instruction for the execution in response to the propriety of the source information. For instance, in a processor system, a processor 1210 uses an intrinsic instruction identifier and tracks the program order of the instruction dispatched during random execution. In an execution stage, when an operand and execution resources for an indicated operation become usable, execution units 1222, 1228 and 1230 execute the instruction received from a dispatch unit 1220 conveniently. |
