Abstract: A multi-core processor system includes a given core among multiple cores, wherein the given core is configured to detect execution of a process by the cores; and generate upon detecting the execution of the process, a specific thread that saves state information indicating an executed state of the process and an executed state of each thread to be monitored of the process.

Abstract: A hierarchical multi-core processor includes a core group for each hierarchy of a hierarchy group constituting a series of communication functions divided according to communication protocol, where a first core group of a given hierarchy among the hierarchy group is connected to a second core group of another hierarchy constituting a first communication function to be executed following a second communication function of the given hierarchy.

Abstract: A multicore processor system includes a processor configured to detect any among a switching process and an assignment process of applications in a multicore processor; acquire upon detecting any among the switching process and the assignment process, a priority level concerning execution of each application assigned to each core of the multicore processor and number of accesses of a shared resource shared by the multicore processor; determine an access ratio of an application whose priority level is highest to each of application remaining after excluding the application whose priority level is highest, among the assigned applications, by comparing the number of accesses by each remaining application and the number of accesses by the application whose priority level is highest; notify an arbiter circuit of the determined access ratios; and arbitrate using the arbiter circuit, the access of the shared resource by the multicore processor, based on the access ratios.

Abstract: A multicore processor system having multiple cores, includes processors configured to measure bandwidth of a network; compare the measured bandwidth and a given threshold; determine among the cores and based on an obtained comparison result, a core adjustment number by which the number of cores executing a given process related to data communicated through the network is adjusted; calculate the number of executing cores after adjustment by the core adjustment number and based on the number of cores executing the given process before the adjustment and the determined core adjustment number; specify a core executing the given process among the cores and based on the calculated number of executing cores after the adjustment; and distribute the communicated data to the specified core executing the given process.

Abstract: A software control device includes a processor configured to determine whether starting software and running software are accessing the same common resource; and control the running software to be temporarily suspended upon determining that the starting software and the running software are accessing the same common resource.

Abstract: An information processing system includes a first apparatus including a position information transmission unit to transmit information on the position of the first apparatus; and a second apparatus including, a position information acquisition unit to acquire a position of the second apparatus; a position information receiving unit to receive the information on the position of the first apparatus; a relative-position information acquisition unit to acquire relative-position information of the second and the first apparatus on the basis of the information on the position of the second and the first apparatus; and a control unit to control a coupling mode of the second and the first apparatus on the basis of the relative-position information.

Abstract: A status notification register storing a state of a function executing section is arranged for each function executing section. The function executing section includes at least one circuit for performing a predetermined function. By determining one of two values set in the status notification register, a power failure occurring in a functional unit is identified and an initial setting process is performed to an identified location when power is restored.

Abstract: A photocurable and thermosetting matte liquid resist composition developable with an aqueous alkali solution is disclosed. The composition comprises in combination (A) a photosensitive prepolymer having a carboxyl group in combination with at least two ethylenically unsaturated bonds in the molecular unit thereof, (B) a photopolymerization initiator, (C) a diluent, (D) an epoxy compound having at least two epoxy groups in the molecular unit thereof, and further (E) a finely pulverized aluminum silicate matting agent in combination with (F) a filler precipitation preventing agent capable of effective thixotropic adjustment in the composition. The composition may further comprise (G) an epoxy resin curing agent. The composition can be advantageously used for the formation of a solder resist on a printed circuit board.

Abstract: A porous ceramic structure adapted in a molten metal container in a way such that the structure pierces the wall of the container for introducing a gas thereinto. The structure comprises a main body made of a porous ceramic material and having a recession on the side adjacent to the outer surface of the container and a sub-body made of a porous ceramic material fitted in the recession of the main body. This ceramic structure enables the operator to make timely judgment for its replacement with new one before it breaks down to cause leakage of molten metal from its container.
