Abstract: A bus control circuit for transferring an exclusive command between first and second bus specifications by mutually converting a first exclusive command of the first bus specification which deals with an exclusive access, and a second exclusive command of the second bus specification which doesn't deal with the exclusive access, includes an exclusive command conversion circuit receiving the first exclusive command, converting and outputting the second exclusive command, when converting from the first to second exclusive commands; an exclusive command generation circuit receiving the second exclusive command and generating the first exclusive command, when converting from the second to first exclusive commands; an exclusive response issuing circuit issuing exclusive response information for the second exclusive command, when converting from the second to first exclusive commands; and an exclusive response receiving circuit receiving exclusive response information for the second exclusive command, when converting from the first to second exclusive commands.
