[57] ABSTRACT

A program storing portion in a data flow type information processor has one input port and two output ports. The two output ports are coupled to a paired data detecting portion through two transmission paths. A program storing portion has a copy function of generating a copy data packet from an original data packet. The original data packet is outputted to the paired data detecting portion through one of the transmission paths from one of the output ports. The copy data packet is outputted to the paired data detecting portion through the other transmission path from the other output port.
