  • Publication number: 20100185833
    Abstract: An object of the invention is to reduce the electric power consumption resulting from temporarily activating a processor requiring a large electric power consumption, out of a plurality of processors. A multiprocessor system (1) includes: a first processor (141) which executes a first instruction code; a second processor (151) which executes a second instruction code, a hypervisor (130) which converts the second instruction code into an instruction code executable by the first processor (141); and a power control circuit (170) which controls the operation of at least one of the first processor (141) and the second processor (151). When the operation of the second processor (151) is suppressed by the power control circuit (170), the hypervisor (130) converts the second instruction code into the instruction code executable by the first processor (141), and the first processor (141) executes the converted instruction code.

  • Publication number: 20070265821
    Abstract: The present invention aims to easily detect incorrect accesses caused by the simultaneous operation of a plurality of circuits and to reduce the time and developing costs required for analyses to specify the incorrect accesses. First and second access order storages prestore access order information representing correct access orders of data to be inputted to and outputted from first and second simulation circuits. First and second access monitors obtain information on the input and output of data to and from the first and second simulation circuits as access information, and judge whether or not an order of obtaining the access information is correct based on the access order information stored in the first and second access order storages. A warning notifier notifies a warning to the user if the order of obtaining the access information is judged to be incorrect.

  • Publication number: 20070245294
    Abstract: An optimum target system is designed by implementing software modules and hardware modules, without discriminating the software modules and the hardware modules one from the other. An external storage stores the software modules including a namespace identifier for identifying the software module, and the hardware modules including a namespace identifier for identifying the hardware module. A module selector specifies a process of a target system to be built, and selects the software modules and the hardware modules that execute the specified process. A namespace manager acquires the namespace identifier for identifying the software module, and the namespace identifier for identifying the hardware module. A module mapping processor implements either one of the software modules and the hardware modules in the target system, based on the namespace identifiers.
