Data flow type information processor

An information processor for processing data packets in accordance with data flow program including a plurality of pairs of destination information and instruction information, comprising:

• program storing means for storing the data flow program, for receiving a first data packet including identification information and destination information, for reading subsequent destination information and instruction information from the data flow program based on the destination information in said first data packet, and for outputting a second data packet including the read out destination information and instruction information and the identification information stored in said first data packet;
• operation processing means for receiving a third data packet including identification information, instruction information and one or two data fields, for performing an operation process with respect to the data in said third data packet based on the instruction information in said third data packet, and for outputting a fourth data packet including data indicating a result of an operation process and the identification information stored in said third data packet;
• merging means for receiving said second data packet from said program storing means and said fourth data packet from said operation processing means, for merging second and fourth data packets having a same identification information and for outputting a fifth data packet including the destination information and instruction information stored in said second data packet and the data stored in said fourth data packet;
• data pair detecting means for receiving an output from said merging means for detecting two fifth data packets having a same destination information and for outputting a sixth data packet including destination information, instruction information and data stored in one of the fifth data packet and data stored in the other fifth data packet;
• and
• branching means for receiving said sixth data packet from said data pair detecting means, and outputting identification information and only the destination information stored in said sixth data packet to said program storing means as the first data packet, and outputting the same identification information and only the instruction information and the data stored in said sixth data packet to said operation processing means as the third data packet, for simultaneously executing process in said program storing means and said operation processing means.

An operating method for a data flow type information processor having a program storing device for storing the data flow program and for reading destination information and instruction information from the data flow program based on inputted destination information, an operation processing device for performing an operation process with respect to inputted data based on inputted instruction information and for outputting data indicating a result of the operation, and a data pair detecting device for outputting data having a same destination information together with the destination information and instruction information, the method comprising the steps of:

• (a) attaching identification information, the identification information indicating correspondence between the destination information being supplied to the program storing device and the instruction information being supplied to the operation processing device, to the destination information and the instruction information or the data;
• (b) merging the destination information and the instruction information read out from the program storing device with corresponding data outputted from the operation processing device based on the identification information;
• (c) receiving an output from the data pair detecting device and outputting the identification information and only the destination information to the program storing device, and outputting the identification information and only the instruction information and the data to the operation processing device;
• and
• (d) simultaneously executing processes in said program storing device and said operation processing device.
