ABSTRACT:
In an arithmetic unit capable of performing arithmetic operations with single byte instructions or a number of bits less than one byte, an instruction which does not specify any register number is executed under the control of a timing control means and a register number stored in a register-specifying memory is selected. When an instruction which does not specify any address is executed under the control of a timing controller, the address information stored in an address-specifying memory is selected, and then the instruction is performed.
