An asynchronous protocol converter, which is capable of flexibly carrying out communications between tens of IP cores in an asynchronous protocol Network-on-Chip system, and which is multiple input multiple output is provided. In an LSI (20), which comprises a plurality of IP cores (21), and routers (22) positioned adjacent to the plurality of IP cores (21), an asynchronous protocol converter (1) is positioned between adjacent routers (22). The asynchronous protocol converter (1) is configured to comprise: a two-to-four-phase converter (11) that is connected to an adjacent router (22a) within the LSI (20); a four-phase pipelined router (12) that is connected on the output side of the two-to-four-phase converter (11); a four-to-two-phase converter (13) that is connected to the outputs of the four-phase pipelined router (12); an input controller (14) that controls the two-to-four-phase converter (11); and an output controller (15) that controls the four-to-two-phase converter (13). |
