Data flow processor and data flow process changing system

摘要

The present invention relates to a data flow process changing system for relieving the process executed in a data flow processor and further for changing the constant in the process of the data flow processor. The data flow process changing system includes a counter section for counting the number of input data, a destination number selecting section for selecting a destination number corresponding to the counted number of input data and a tagging section for forming a packet. When a destination number corresponding to the counted number of input data is selected in the data flow process changing system, the program executed in the data flow processor can be changed. In the data flow process changing system, a constant change data generating section is responsive to a constant change request to generate a constant change data, and a destination number selecting and tagging section forms a packet addressing the destination number of a constant change program. When the packet is provided to the data flow processor, the constant change program updates the constant of the constant table store, in which the constant used in the main program has been stored, to a predetermined constant.
