To obtain a high performance computer decreased in the number of commands to be executed. A control circuit receives a command (CMD), and outputs a special command signal which becomes "H" when the command (CMD) instructs "push" command, to a register file. The register file, when the special command signal is "H", outputs the stored data value of register as register data regardless of the values of read register address signals, and and outputs the stored data value of register as register data. An ALU adds the register data and control data, and outputs the ALU operation result to the register file. An address adder adds the register data and control data, and outputs the address addition result to an external memory.
