Abstract
In a processor, a plurality of instructions in a program are executed in parallel using a plurality of functional units within the processor. Determination of which functional unit is to be used to execute each instruction is made when the program is produced prior to execution. The processor has the priority as to access of the PSW among the plurality of functional units predetermined when the contents of a PSW (Program Status Word) storage register in the processor are to be accessed simultaneously by a plurality of instructions during parallel execution of a plurality of instructions. Execution control can be provided of a program that reliably avoids a PSW access a conflict by a plurality of instructions during parallel execution of a plurality of instructions using a plurality of functional units in the processor.
