ABSTRACT:
A general-use register set includes a plurality of registers in a central processing unit body. A register-bank memory has memory regions relevant to the plurality of registers and is connected to the central processing unit. An output signal of an address circuit included in the central processing unit is supplied to the register-bank memory. Alternatively, an output signal of a decoding circuit included in the central processing unit may be supplied to the register-bank memory. A signal for selecting either activation or deactivation of the register-bank memory is a signal which indicates a selection of the deactivation of the register-bank memory except in a case where data is written in the general-use register set and a case of a restoration operation after register bank switching. Instead, a signal for selecting either generating or non-generating of a clock signal for the register-bank memory may be a signal which indicates a selection of the non-generation of the clock signal for the register-bank memory except in a case where data is written in the general-use register set and in a case of a restoration operation after register bank switching.
