Data driven processor with improved initialization functions because operation data shares address space with initialization data

摘要

A data driven type information processor includes a firing control unit, an operation unit, and a program storage unit. Each of these units has a function of initializing itself in response to an initialization data packet in a specific form. The data driven type information processor further includes a static memory connected to the operation unit for storing in the same address space data required for operation and data for generating an initialization data packet for initializing the firing control unit, the operation unit, and the program storage unit; an initialization information read unit responsive to an initialization request for generating an initialization data packet based on the data for generating an initialization data packet read out from the memory and applying the generated data packet to at least one of the firing control unit, the operation unit, and the program storage unit; a merge unit for merging externally applied data packets and data packets generated in the data driven type information processor for applying the merged data packets to the firing control unit; and a branch unit for providing to the merge unit or to the outside of the data driven type information processor the data packets provided from the program storage unit according to destination information included therein.
