PURPOSE:To efficiently perform the processing of a list data of list form, by performing the processing of the list data separately from that of an atom data. CONSTITUTION:A structure processing part is constituted of a memory device 1, a transfer device 2, an arithmetic unit 8, and a conditional register 4, and a value processing part is constituted of a second register device 5, a second arithmetic unit 6, and a second memory device 7. The list data accumulated in the memory device 1 is transferred to the register device 3 in a processing unit 3 by the transfer device 2 via a shift device, and the arithmetic calculation of a CAR operation and a CDR operation are performed. The reference of the atom data is stored in a VALUE part of list form for each element, and it is stored from the processing unit 3 to the second memory device 7, and is stored to the second register device 5 by accessing to the memory device 7. Arithmetic processings are performed in the second register device 5, and the second arithmetic unit 6, and the results of the processings are stored in the second memory device 7 again.
