ABSTRACT:
By doubling an arbitration circuit for bus access command to be requested to a bus, the number of bus cycles occupied per one bus access command is reduced by one cycle to allow the bus to be operated at high speed. A first in-module arbiter selects a bus access command having the highest priority to be issued to the bus, and a second in-module arbiter selects the bus access command having the highest priority excepting the bus access command previously requested last time by the one module. If the module had already acquired the bus last time, then the result of the second in-module arbiter is selected as a current bus access command. On the other hand, if the module did not acquire the bus last time, then the result of the first in-module arbiter is selected as a current bus access command.
