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. These transfers include: (1) dumping a loaded program data packet to a von Neumann processor during loading of other program data packets for on-line verification of proper loading; and (2) outputting an operation result, of an operation process performed by the data driven processor, to the von Neumann processor for verification of proper operation processing during the continued operation processing of the data driven processor.
