    摘要: A resource management apparatus comprises an information selection unit having an operation speed different to an operation speed of a common resource and selecting from information transferred from a plurality of bus masters, a buffer unit for storing the information selected by the information selection unit, and a timing adjustment unit for controlling timings of the information selections in the information selection unit. The information selection unit selects the information comprised of a command and data transferred from any of the plurality of bus masters to the common resource. The timing adjustment unit controls the timings of the information selections in the information selection unit so that the sum of time required for selecting a plurality of predetermined volumes of information in the information selection unit and the sum of processing time in the common resource are substantially equal to each other.

    摘要: Bandwidth information including a plurality of slots each having highest priority order information for arbitrating access conflict, and priority master information for specifying, as a priority master, one or more of a plurality of masters whose latency in accessing a memory serving as a shared resource is desired to be reduced are included as arbitration information. When an arbitration section arbitrates access conflict while switching the slots in the bandwidth information at each of predetermined arbitration timings, if there is an access request from the priority master specified in the priority master information, the arbitration section changes the sequence of the slots in the bandwidth information so as to allow the priority master to access the memory with priority.

    摘要: 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.

    摘要: A transmission cancellation section is provided on a bus connecting a master and a slave. During a reset of the master, the transmission cancellation section blocks the bus so that an invalid command flowing on the bus does not reach the slave and executes, instead of the master stopped by the reset operation, generation of data which corresponds to an access request command already output to the slave and is to be sent to the slave and receiving of data from the slave.

    摘要: A bus arbitration part for arbitrating access requests from bus masters includes an arbitration history management section that records absence of an access request from any bus master at a given basic arbitration timing. Based on this record, an access request arbitration section issues access permission for an access request issued after the given basic arbitration timing without a wait for the next basic arbitration timing.

    摘要: A clock enable (CKE) control circuit (112) is provided between a memory control circuit (111) and a SDRAM (120). When a system is in, e.g., a sleep state, the CKE control circuit (112) controls a CKE signal outputted to the SDRAM (120) such that it is fixed to a Low level. As a result, it is possible to halt a power supply provided to the memory control circuit (111), while maintaining the low-power-consumption mode of the SDRAM (120), so that power consumption resulting from a leakage current is suppressed. In addition, it becomes also possible to reset the memory control circuit (111), while maintaining the low-power-consumption mode of the SDRAM (120).
