Abstract
The data processing system has a data processing function to perform a data processing by specifying one of a plurality of register groups according to an instruction. The instruction contains information for indicating a change from one register group to another register group and information for specifying a desired one or two or more registers in said register group. This makes it possible to transfer the contents of the desired one or two or more registers to other registers at the time of a register change.
