PURPOSE:To improve the transfer efficiency by securing the 1:1 correspondence between a token processor which obtains the node information from a program token and a node on a program. CONSTITUTION:The address registers of a token processor 20 connected in parallel to a bus are connected in series. A comparator 28 compares the contents of an address register 22 of the processor 20 with those of an external address bus 21. When the coincidence is obtained, the contents of a data bus 23 are fetched by the processor 20. If the data contents are equal to the processing data, the contents are sent to a data register 24. While the data contents are sent to a program register 25 when they are equal to the node information. When data are supplied to the register 24, a detecting circuit 26 decides whether the arithmetic conditions are fixed as indicated or not. If these conditions are fixed, the results obtained by a computing element 27 are delivered to a prescribed address. Thus the length of data token can be reduced.
