Zusammenfassung:PROBLEM TO BE SOLVED: To achieve to gather and scatter multiple data elements. SOLUTION: Efficient data transfer processing can be achieved by: a step of decoding by a processor device, a single instruction specifying transfer processing for a plurality of data elements between a first storage area and a second storage area; a step of issuing the single instruction for execution by an execution unit in the processor; a step of detecting the occurrence of an exception during execution of the single instruction; and in response to the exception, a step of delivering pending traps or interrupts to an exception handler before delivering the exception.
