摘要： A processor according to the present invention includes a decoding unit, an operation unit and others. When the decoding unit decodes an instruction “vxaddh Rc, Ra, Rb”, an arithmetic and logic/comparison operation unit and others (i) adds the higher 16 bits of a register Ra to the lower 16 bits of the register Rb, stores the result in the higher 16 bits of a register Rc, and in parallel with this, (ii) adds the lower 16 bits of the register Ra to the higher 16 bits of the register Rb, and stores the result in the lower 16 bits of the register Rc.

摘要： A processor for sequentially executing a plurality of programs using a plurality of register value groups stored in a memory that correspond one-to-one with the programs. The processor includes a plurality of register groups; a select/switch unit operable to select one of the plurality of register groups as an execution target register group on which a program execution is based, and to switch the selection target every time a first predetermined period elapses; a restoring unit operable to restore, every time the switching is performed, one of the register value groups into one of the register groups that is not selected as the execution target register group; a saving unit operable to save, prior to the restoring, register values in the register group targeted for restoring, by overwriting a register value group in the memory that corresponds to the register values; and a program execution unit operable to execute, every time the switching is performed, a program corresponding to a register value group in the execution target register group.
