  • Patent number: 7779175
    Abstract: The present invention introduces the notions of a rendezvous component and rendezvous functionality into the communications network environment. Using the invention, an application can express information regarding when an operation requested of a device should complete and at which location, and it enables the device to perform its operations respecting this information while also improving the device's overall behavior. In an embodiment, one or more data objects are distributed across one or more collections of storage devices using a dispersal technique. When access to a data object is desired, a rendezvous component issues a set of constituent requests to the collections of storage devices. These requests typically include location and timing rendezvous parameters specifying a destination location where and a given time when a given data object is to be reconstituted.

  • Patent number: 7779172
    Abstract: A DMA controller controls DMA transfer in an information processing system. Input and output devices are a transfer source or a transfer destination in DMA transfer and request DMA transfer. A DMAC activating unit is provided with an event monitoring unit and an event register. The event register registers an event subject to monitoring. The event monitoring unit detects an event generated in the input and output devices and determines whether the detected event matches an event registered in the event register. If it is determined that the events match, the event monitoring unit activates the DMA controller.

  • Patent number: 7774513
    Abstract: A DMA circuit operates a plurality of DMA channels in parallel, enabling reduction of the circuit scale and fewer development processes. A channel manager circuit reads in sequence the control information for each DMA channel from control memory, performs analysis, and according to the divided DMA control sequence, performs state processing (DMA control). Further, the channel manager circuit updates the control information, writes back the control information to the control memory, and executes time-division control of the plurality of DMA channels. Hence the circuit scale can be reduced, contributing to decreased costs, and the number of development processes can be reduced.

  • Patent number: 7774520
    Abstract: A new audio playback architecture may be used, which allows the use of much larger buffering than that used by a typical audio subsystem in a computing system to improve power efficiency of the system and at the same time allows to maintain the quality (e.g., fidelity and responsiveness) of the audio playback. The audio controller in the new architecture may be made to report back to the host system a more accurate indication of which audio frame is being set to the audio codec than a currently available audio controller does. Additionally, the controller is capable of re-fetching previously buffered (but not yet transmitted) data. Furthermore, buffers in both the audio controller and the main memory may be dynamically adjusted during playback of audio data and/or for different applications.

  • Patent number: 7774508
    Abstract: An electronic apparatus that transmits error information about setting of a block size to a host device includes an interface section that transmits and receives a command, a response and data to and from the host device. When the data is a predetermined length or more, the interface section executes multi-block transmission. Moreover, the electronic apparatus includes a data buffer, and a storage section that stores information about a block size. When the interface section receives a block size setting command transmitted from the host device and the block size is larger than a capacity of the data buffer, it transmits a response including error information about incapability of accepting the block size at the time which has a predetermined relation to the block size setting command.

  • Patent number: 7774514
    Abstract: A method of transmitting data between storage virtualization controllers (SVCs) in a computer system is disclosed, in which there is an inter-controller communication channel (ICC) between the storage virtualization controllers. The method comprises the steps of: a central processing unit (CPU) of one storage virtualization controller (SVC) sending a data transfer request to an interface that establishes the ICC when the CPU needs to transmit information to the other SVC; and transmitting the information to the other SVC after the interface that establishes the ICC receives the data transfer request, and obtains the information.

  • Patent number: 7769983
    Abstract: A method and apparatus for caching instructions for a processor having multiple operating states. At least two of the operating states of the processor supporting different instruction sets. A block of instructions may be retrieved from memory while the processor is operating in one of the states. The instructions may be pre-decoded in accordance with said one of the states and loaded into cache. The processor, or another entity, may be used to determine whether the current state of the processor is the same as said one of the states used to pre-decode the instructions when one of the pre-decoded instructions in the cache is needed by the processor.

  • Patent number: 7769923
    Abstract: Method of managing interaction between a host subsystem and a peripheral device. Roughly described, the peripheral device writes an event into an individual event queue, and in conjunction therewith, also writes a wakeup event into an intermediary event queue. The wakeup event identifies the individual event queue. The host subsystem, in response to retrieval of the wakeup event from the intermediary event queue, activates an individual event handler to consume events from the individual event queue.

  • Patent number: 7761647
    Abstract: A storage device with automatic-switching function is disclosed. When the storage device is coupled to a USB interface, the power provided by the USB interface turns the USB/SATA converter on to convert data from the USB interface into SATA format and transmit to a hard disk. When the storage device is coupled to a SATA interface instead of the USB interface, the power provided by the USB interface does not turn the USB/SATA converter on to convert data. In this way, the data from the SATA interface directly transmit to the hard disk.

  • Patent number: 7761619
    Abstract: Disclosed are methods for handling RDMA connections carried over packet stream connections. In one aspect, I/O completion events are distributed among a number of processors in a multi-processor computing device, eliminating processing bottlenecks. For each processor that will accept I/O completion events, at least one completion queue is created. When an I/O completion event is received on one of the completion queues, the processor associated with that queue processes the event. In a second aspect, semantics of the interactions among a packet stream handler, an RDMA layer, and an RNIC are defined to control RDMA closures and thus to avoid implementation errors. In a third aspect, semantics are defined for transferring an existing packet stream connection into RDMA mode while avoiding possible race conditions. The resulting RNIC architecture is simpler than is traditional because the RNIC never needs to process both streaming messages and RDMA-mode traffic at the same time.

  • Patent number: 7761620
    Abstract: A communications buffer and control unit that configure a USB connection endpoint are provided connected by a USB bus to a host device. The control unit changes the receive buffer size of a receive buffer where the communications buffer stores receive data, based on an instruction that is sent from the host device side through USB virtual serial communication, to enable the reception of real-time execution commands by the communications device. This enables the reception of real-time execution commands when the receive buffer on the communications device side is in a buffer-full state in data communications between a host device and a communications device.
