DATA FLOW TYPE COMPUTER

PURPOSE:To curtail the quantity of a hardware by making a titled computer execute a data flow program by coupling annularly a link memory unit, a queuing control unit, an instruction memory unit and an execution unit. CONSTITUTION:When a token (x) arrives at a link memory unit 11, an address L1 is read out, and an operand packet OP is assembled and sent to a queuing control unit 12. When an operand packet OP' which passes through the unit 12 without stopping arrives at an instruction memory unit 13, an address N1 is read out, and an instruction packet IP is assembled and sent to an execution unit 14. In the unit 14, an instruction packet is fetched from an input queue, an operand data is read out of a data memory, compared and calculated by an operating unit, and as a result, a packet is assembled, and sent to the unit 11 through a queue stack 15 by an output controller. In the unit 11, an address L2 is read out, and thereafter, a calculation is advanced circularly and a processing of a data flow is executed.
