PURPOSE:To indicate an executable node, by storing control tokens concerning the same node and a pointer for this node in individual words of a node drive register. CONSTITUTION:A processor unit PU reads out a complete token packet CTP, where control tokens are stored, from a node drive register NDR. At this time, an indicator of a part TS which indicates that words are accessed is turned on. The processor PU finds an executable node by a node pointer NPR part of the read-out packet CPT and executes the processing. After the processing, a pointer to the next node and control tokens are connected, and a new token packet TP is sent to the register NOR. In the register NDR, control tokens for the same node are collected with the associative function. After transmitting all packets TP, the processor PU turns off the indicator of the part TS and subtracts one from values of TC1-TCj. (j) is a variable of an input arc determined by the node to which the current TP is sent.
