  • Patent number: 9043524
    Abstract: An information processing apparatus includes a plurality of modules connected in a ring shape via a bus, and each module processes a packet flowing in a single direction on the ring in a predetermined order. The module includes a communication unit for transmitting a packet received from a first direction in the ring via the bus to a second direction, a discrimination unit for discriminating a packet from among the packets received from the first direction as a processing packet to be processed by the module, and a processing unit which is connected with the communication unit one by one and configured to process the processing packet. The communication unit transmits the packet processed by the processing unit at an interval equivalent to processing time or more for a processing packet processed by a module in a latter stage in the predetermined order among packets transmitted by the communication unit to the second direction.

  • Patent number: 8954633
    Abstract: In an information processing apparatus in which data processing is performed in a predetermined sequence by processing modules connected to a ring bus, if an amount of data generated by input data in the ring bus is not considered, the data amount exceeds an amount of data that can be held by the processing modules on the ring bus, and a data collision often occurs, so that processing efficiency of the ring bus deteriorates. An amount of data input into the ring bus is controlled so that the total sum of data amounts output to the ring bus from processing units used for processing does not exceed a maximum amount of data that can be held by the processing modules on the ring bus.

  • Patent number: 8104661
    Abstract: A solder bump is formed on a substrate by using a heating device where a lid structure blocks hot air from directly blowing against a solder composition. The heating device can reduce high-temperature oxygen molecules that come into contact with the solder composition, oxidation of the solder composition is suppressed. As a result, although the hot air is used for heating, a solder bump can be formed by the liquid-like solder composition. Further, because the lid structure is uniformly heated by the hot air, radiation heat from the lid structure is also uniform, and a container is more uniformly heated. In addition, because the hot air is suppressed from directly blowing against a liquid surface, the liquid-like solder composition is not scattered by the hot air.
