Abstract
A resource management device of the present invention, used in a system where at least one bus master is connected to each of a plurality of buses, includes: a bus arbitration section for arbitrating an amount of access to be made from the buses to a shared resource; an arbitration information management section for managing, as bus arbitration information, a bus priority order and a highest access priority pattern for ensuring a predetermined access bandwidth to the shared resource for each bus for an arbitration operation by the bus arbitration section; and a resource control section for controlling, based on characteristics of the shared resource, an access to the shared resource from the bus whose access request has been granted by the bus arbitration section. Thus, it is possible to guarantee a minimum bandwidth for access to the shared resource for each of the plurality of bus masters.
