    摘要: In a vehicle electronic system including a plurality of LSI boards, LSIS which cannot control a user interface such as image or audio directly issue a command for notifying a vehicle occupant of its own information via networks and an information control LSI receives the request to output a message. A mechanism for setting priority of processings regarding LSI status information notification to be lower than that of an apparatus control processing is provided in each of LSIs and networks so that real-time property of the apparatus control processing is maintained. In order to reduce network load regarding the LSI status information notification, a message content itself is stored in a memory in a vehicle information processing unit previously so that only an ID for identifying the message content is transmitted.

    摘要: The information processing device comprises first and second master circuits and an arbiter for arbitrating access rights to a bus to which the master circuits are connected. The arbiter has storage units retaining information representing priorities of the access rights, and an arbitration control logical unit for arbitrating the access rights of the master circuits based on the information. When the priority of the first master circuit is higher than the priority of the second master circuit and there is no access request from the first master circuit but there is an access request from the second master circuit, the arbitration control logical unit permits access of the second master circuit, and the storage units lower the priority of the second master circuit without changing the priority of the first master circuit.

    摘要: A chip (1) includes: a resource manager (2); various kinds of functional blocks (3-6); a thermal sensor (13); and a performance counter (15). The resource manager manages tasks that the functional blocks execute, and determines a task progress (38) for each task from an activated ratio (α) provided from the performance counter and a deadline (39) contained in task information (33) and decides priority of each task. When the temperature detected by the thermal sensor during execution of a task is not less than a threshold (T_max), the resource manager reads out a power consumption budget (P_max) from a memory (9) which has been set to make the temperature below the threshold, and stops the clock fed to the functional block executing a task having a lower priority or lowers the frequency of the clock until a chip power consumption value (p_sum) becomes smaller than the power consumption budget.

    摘要: A data processing device which, even if congestion occurs on a bus circuit of a specific processing circuit in an LSI in which multiple circuit modules are connected by buses, can fully actualize the performance potential of the system on chip. Buses and slave circuits on which accesses concentrate are provided with observation blocks. Each observation block has a mechanism to notify system control circuits such as a clock controller and master circuits such as CPU cores of the acquired status information, and each master circuit further has a mechanism capable of dynamically altering the priority order for notifying the bus circuits and slave circuits of the priority order of processing.
