Abstract:
A bus emulation comprising:a hub circuit; a plurality of serial interface circuits; and serial transfer paths for connecting said plurality of serial interface circuits and said hub circuit and being installed on a large scale integrated circuit or a print circuit board, said serial interface circuit comprising: a parallel to serial conversion circuit for converting parallel data from a peripheral circuit connected to the serial interface circuit to a serial data and supplying to said serial transfer path; and a serial to parallel conversion circuit for converting serial data supplied from said hub circuit via said serial transfer path to a parallel data and supplying to said peripheral circuit; and said hub circuit supplying the serial data supplied from said serial interface circuit via said serial transfer path to a serial interface circuit connected to a peripheral circuit as a transfer destination of said parallel data among said plurality of serial interface circuits via said serial transfer path, wherein said hub circuit divides said plurality of serial interface circuit into a plurality of groups for performing data transfers in advance and relays the serial data between said serial interface circuits so that parallel data is transferred in said respective plurality of groups.
