Data flow processor which combines packets having same identification and destination and synchronizes loop variables for detecting processing loop termination

DETAILED DESCRIPTION An object of the present invention is to provide an execution control system of a data flow program which can eliminate the above described problems and which has a high efficiency of a program execution and uses simple hardware.
According to the data flow type information processor of the present invention, identifier (color) information for identifying different data sets is applied to a data packet, and means for determining the condition of a loop termination is adapted to determine completion of one cycle in the loop structure.
According to the present invention, the number of operators and the number of instruction executions required for assuring completion of one cycle in the loop structure can be reduced, and loop processing between different data sets can be executed in parallel.
As a result, efficiency of program execution can be increased.
In addition, only one kind of token can be used, so that data and control processing can be handled in a unified manner, resulting in simplification of hardware.
These objects and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.
