  • Publication number: 20210011716
    Abstract: Information processing circuit includes an accelerator function unit (AFU), an FPGA interface unit (FIU), a tag check unit, and an output control unit. The AFU sequentially obtains write control instructions for a plurality of kinds of data including an output waiting instruction that stops output of a subsequent instruction. The FIU sequentially outputs the write control instructions via a first path or a second path. The tag check unit receives responses to the write control instructions output from the FIU. The output control unit selects one of the first path and the second path based on the storage address of the write control instruction, determines the necessity for mixing write control instructions, mixes write control instructions and causes the FIU to output the result.
