PROBLEM TO BE SOLVED: To optimize a connection constitution between a slave bus and a slave module without increasing a circuit scale, in a bus system using a crossbar switch.SOLUTION: When master modules #1(11)-#3(13) access any of a plurality of slave modules on the basis of a memory map in which mapping addresses different in the number of bas bridges #1(21)-#3(23) in each of slave modules #1(41)-#4(44) are allocated, a slave module interface unit 41a selects one of bus signals output from the plurality of bus bridges via slave buses 30 (30a, 30b and 30c) on the basis of a set slave selection signal. |
