MULTIBUS INTERFACE MODULE AND MULTIBUS SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a multibus interface module which does not need a bus arbiter and which can easily design an efficient multibus system and a multibus system provided with the multibus interface module.;SOLUTION: The multibus interface module RB_HB2 is provided with a plurality of intermediate internal interface modules FMn3 mutually serially connected. The individual FMn3 can connect an input link from an upstream RB_HB2 or an input link from a function block FB1 to an output link on the opposite side to FB1 or an output link to a downstream RB_HB2 and can connect an input link from the opposite side to the FB1 or the input link from the upstream RB_HB2 to the output link on the side of FB1. Thus, the respective FMn3 determine data routing paths and so can provide the multibus system which does not need the bus arbiter.;COPYRIGHT: (C)2008,JPO&INPIT
