PURPOSE:To make the operation between different codes easy, by selecting and outputting a register storing the 1st kind code information being the objective of processing and a code conversion memory storing the 2nd kind code information corresponding to the register. CONSTITUTION:The 1st kind code information A0, B0 being the processing objective are stored in registers 101a, 101b. Values and symbols corresponding to the 1st kind code are stored in the 2nd kind code at each address location indicated with the 1st kind code information of code conversion memories 102a, and 102b. Through the output of a code conversion control flag 104, selectors 103a, 103b are controlled, and the selector 103a selects an output signal A1 of the register or an output signal A2 of the conversion memory. The selector 103b is similarly operated. A comparator 20 operates signals A3 and B3 and outputs C the result. Thus, the operation between different codes can simply be performed as same as that of the same kind codes. |
