  • Patent number: 8185683
    Abstract: Transparency of resources is provided and ordering in an access is guaranteed between nodes on a computer network. In an information processing system in which a plurality of processor units are connected to each other by a switch, a global address space is introduced into which effective addresses of the processor units are mapped and which is shared by the plurality of processor units. In response to an access request packet issued by a processor unit and designating an effective address of a target node, a bridge for routing an input and output bus of a processor unit to an input and output bus of the switch converts the effective address of the target node into a global address by appending to the packet a node identification number identifying the target node, and outputs the access request packet designating the global address to the switch. After an access request packet for a write operation is output, the bridge confirms whether the write operation is completed in a target node.

  • Patent number: 8095718
    Abstract: A downstream port 22 of a bridge 20 connecting a processor unit and a peripheral device acknowledges access from the peripheral device via one of a plurality of downstream channels available for access by the peripheral device to a memory of the processor unit, the downstream channels being virtual channels provided for interfacing with the peripheral device. The router 24 routes the access to upstream channels each assigned a memory bandwidth available for access to the memory, the upstream channels being virtual channels supported by the processor unit. In this process, the router refers to a table storing identifiers of the downstream channels and identifiers of the upstream channels in association with each other so as to allocate to the peripheral device the upstream channel corresponding to the downstream channel used by the peripheral device, in response to the access from the peripheral device.

  • Patent number: 8006000
    Abstract: There is provided a technique of accessing a memory of a processor from a peripheral device, thereby the security is ensured while efficiency is being pursued. An address converter 14 includes an address conversion table for converting an effective address into a physical address. The address conversion table stores the effective address to which an area in a memory of a processor unit 10 is allocated to each peripheral device 30 and identification information of an access source to which access permission is given, in association with each other. When the peripheral device 30 accesses, the address converter 14 determines to permit access to the effective address under the condition that the device identification information, included in an access request packet, by which the peripheral device 30 can be uniquely identified, matches the identification information of the access source corresponding to the effective address, in the address conversion table, designated by the access request packet.

  • Publication number: 20090235048
    Abstract: Introduced is an end-point bridge that relays an end point—formed by an external bus in a device tree managed by a first processor unit and an end point formed by an external bus in a device tree managed by a second processor unit. A conversion unit in the end-point bridge replaces a requestor ID contained in an access request packet, for example, which has reached the end point, to the ID of the end point from the ID of a host bridge. The ID of the host bridge is stored in a memory in a manner that the ID of the host bridge is associated with a tag of the packet, and is used to return the requestor ID when a response packet to the request reaches the end point.

  • Patent number: 6851535
    Abstract: A tuning method for the exciting current-transmission torque characteristic of a power transmission apparatus is provided. A yoke (36), which supports an electromagnet (33), is accommodated in a groove (53) and is apart from the groove by a first distance (L2) and a second distance (L4). The exciting current-transmission torque characteristic is tuned by varying the first distance while keeping the second distance fixed. When the first distance is varied, the variation of the magnetoresistance of a magnetic path is relatively small. Therefore, the exciting current-transmission torque characteristic is more accurately tuned.

  • Patent number: 4646070
    Abstract: The degree of deterioration of lubricating oil used in an internal combustion engine is detected by measuring the lubricating oil dielectric constant with a pair of spaced sensor capacitor electrodes in the lubricating oil. The sensor capacitor is connected to a fixed capacitor to form a voltage divider connected across a constant frequency AC voltage source so that a developed voltage across the sensor capacitor corresponds to the lubricating oil dielectric constant. The frequency of the AC voltage is set at a value ranging from 50 KHz to 500 KHz.

  • Patent number: 4616615
    Abstract: In a Diesel engine with a Bosch-type fuel pump or the like having a control lever which determines the fuel injection quantity, idling speed is controlled by a movable stopper which abuts the control lever to place a lower limit on fuel injection quantity during idling. A control unit derives a target idling speed value according to engine temperature, electrical load, etc. and controls the pneumatic actuator of the stopper in accordance with the difference between actual engine speed during idling and the target idling speed. When the engine is not idling, the pneumatic actuator may be controlled to act as a dashpot, damping the return of the control lever to its idling position. Electromagnetically controlled valves respond to the control unit by providing atmospheric pressure or negative pressure to the pneumatic actuator. An auxiliary valve is provided for bypassing a defective atmospheric pressure supplying valve.
