Abstract
Abstract A data flow information processing apparatus includes one or a plurality of data driven type processors for processing data packets based on a data flow program, one or a plurality of memories accessed by these processors, and a router receiving data packets processed by these data processors for selecting a path for selectively applying the data packet to any of the one or the plurality of memories. More preferably, a first router includes an address calculating unit for calculating the address based on the content of the data packet, and a branching unit for branching the path of the data packet based on the calculated address. The data packet includes a generation number allotted in accordance with the order of input time and data. The address calculating unit includes a unit for calculating a modified address by modifying the generation number based on the data. The address modifying unit may include a circuit for modifying the generation number with a prescribed global offset, and a circuit for calculating a locally offset address by further modifying the generation number with the data included in the applied data packet.
