Attorney, Agent or Firm:

A data driven processor includes an H register storing output destination information in path connection verification, and a circuit for selectively providing a data packet to one of a plurality of output ports according to a path verification flag and destination information included in an input data packet and the contents of the H register. The processor 250 may further include a circuit for applying a data packet to an image memory unit according to a path verification flag included in the input data packet and the contents of the H register, and a circuit for directly providing to the output processing unit a data packet for testing returned from an image memory unit according to the path verification flag thereof. A data driven information processing device including a plurality of data driven processors and a method of verifying a path connection in this data driven information processing device are also disclosed.

DETAILED DESCRIPTION An object of the present invention is to provide a data driven processor that can easily carry out verification of a path connection in a data driven information processing device irrespective of constraints imposed on the contents of a data packet for normal processing.
Another object of the present invention is to provide a data driven information processing device that can easily verify a path connection in a data driven type information processing device irrespective of constraints imposed on the contents of a data packet for normal processing, in addition to normal processing.
A further object of the present invention is to provide a data driven information processing device that can easily verify a path connection in a data driven information processing device having a connection in which an output path branches into two irrespective of constraints imposed on the contents of a data packet for normal processing.
Still another object of the present invention is to provide a data driven information processing device that can easily verify, irrespective of constraints imposed on the contents of a data packet for normal processing, a path connection in a data driven type information processing device having a connection in which an output path branches into two and including a predetermined memory device such as an image memory device.
A still further object of the present invention is to provide a data driven information processing device that can make it easy to verify, irrespective of constraints imposed on the contents of a data packet for normal processing, a path connection in the data driven information processing device having a connection where two transmission paths are merged into one, and including a predetermined memory device such as an image memory device.
Yet a further object of the present invention is to provide a data driven information processing device that can make it easy to verify, irrespective of constraints imposed on the contents of a data packet for normal processing, a path connection in the data driven information processing device having a connection in which a transmission path branches into more than 1 path, and including a predetermined memory device such as an image memory device
