  • Debugging system for the loading and execution of data flow programs
    Patent number: 5511215
    Abstract: A data processing system includes a data driven processor for carrying out a plurality of different information processing in parallel using respective plurality of provided data packets, a router, and a plurality of von Neumann processors. When a von Neumann processor provides program data packets to the data driven processor via the router to carry out program loading in the data driven processor, another von Neumann processor provides to the data driven processor a data packet storing dumping information via the router. The data driven processor dumps and provides a loaded program data according to the dumping instruction of the provided packet. Therefore, a plurality of von Neumann processors can be connected on-line to at least one data driven processor to carry out in parallel a plurality of different types of data transfer between the data driven processor and each von Neumann processor.

  • System having multiple data flow processors and switching unit for selectively supplying packets containing data from packet transmitter to any selected data flow processor
    Patent number: 5499347
    Abstract: A system having multiple data flow processors is provided which can independently test the operation of each individual data flow processor so that any failure found in the test will easily be located. A host computer is selectively connected to one of a plurality of data flow processors through a switching unit. The switching unit can select one of the data flow processors which can independently be tested.

  • Data driven type information processing apparatus capable of processing untagged data having no tag information
    Patent number: 5452464
    Abstract: A data driven type information processing apparatus includes an information processing unit for carrying out an operation process according to a data flow program based on a data packet with a tag attached thereto, and a tag attaching unit provided in an input stage of the information processing unit. The tag attaching unit attaches a prescribed tag to data without a tag, which is applied externally or from another information processing apparatus connected on-line to generate a tagged data packet, and applies the tagged packet to the information processing unit. An information processing apparatus which is connected on-line to the present information processing apparatus and mutually exchanges the processed data mutually is not limited to either von Neumann type or non Neumann type (data driven type).
