Abstract
A control circuit for data transfer between a main memory and a register file. Firstly, the control circuit acquires, via a selector, a save area mask (SAM) data from external circuitry. A register file address generator produces a register file address using the SAM data which has been chosen by the selector. The register file address determines a location of a register in the register file. A SAM data renewal circuit is provided to renew the SAM data selected by the selector. The SAM data which has been renewed will be used for addressing another register in the register file. The renewal circuit supplies the selector with the SAM data which has been renewed. A controller is arranged to receive the SAM data chosen by the selector and generates a control signal according thereto. The control signal is applied to the selector and controls same such as to select the SAM data from the external circuit or the SAM data applied from the SAM data renewal circuit.
