  • Patent number: 8656105
    Abstract: A second level memory controller uses shadow tags 711 to implement snoop read and write coherence. These shadow tags are generally used only for snoops intending to keep L2 SRAM coherent with the level one data cache. Thus updates for all external cache lines are ignored. The shadow tags are updated on all level one cache allocates and all dirty and invalidate modifications to data stored in L2 SRAM. These interactions happen on different interfaces, but the traffic on that interface includes level one data cache accesses to both external and level two directly addressable lines. These interactions create extra traffic on these interfaces and creating extra stalls to the CPU. Thus in this invention shadow tags are updated only on a subset of less than all updates of the level one tags.

  • Patent number: 8627000
    Abstract: Described is a technology by which a virtual hard disk is able to continue servicing virtual disk I/O (reads and writes) while a meta-operation (e.g., copying, moving, deleting, merging, compressing, defragmenting, cryptographic signing, lifting, dropping, converting, or compacting virtual disk data) is performed on the virtual disk. The servicing of virtual disk I/Os may be coordinated with meta-operation performance, such as by throttling and/or prioritizing the virtual disk I/Os. Also described is performing a meta-operation by manipulating one or more de-duplication data structures.

    Abstract: System and method for configuring a portable device. The portable device includes a serial bus hub, one or more processors coupled to the serial bus hub via a serial bus, and a flash memory coupled to the serial bus hub via the serial bus. A degraded signal is received to a serial bus hub included in the portable device via a serial bus, where the degraded signal includes code to be written to the flash memory to initialize or update firmware for the portable device. The serial bus hub restores the degraded signal, thereby generating a restored signal, and sends the restored signal to at least one of the one or more processors to initialize or update the firmware in the flash memory for the portable device.

  • Patent number: 8601230
    Abstract: A volume migration method for causing to carry out a migration from a first volume manager to a second volume, includes: by causing the first volume manager to carry out actual accesses, obtaining information of correspondence, by the first volume manager, between logical volume offsets and physical blocks on a physical medium; judging, based on the obtained information of the correspondence, whether or not an exceptional data layout is carried out; and when it is judged that the exceptional data layout is not carried out, updating only a header area on the physical medium for the second volume manager. Incidentally, the aforementioned obtaining is carried out by using a program module for blocking access by the first volume manager to the physical medium. Thus, when only the header area is updated after it is confirmed the exceptional data layout is not made, the high-speed volume migration becomes possible.

  • Patent number: 8117423
    Abstract: Instructions asserted in the instruction pipeline (3) of the microprocessor are accompanied by control information, comprising a group of bits, asserted within a control information pipeline (15) of the processor. The control information pipeline is synchronized to the instruction pipeline so that the control information for an instruction progresses in synchronism with the instruction. The control information may identify, directly or indirectly, the type of operation called for by the instruction and, if the operation is to be performed in parts, indicate the part to be performed. Means are included in the processor, such as a number of functional execution units (7), to interpret that control information and take appropriate action.

  • Patent number: 8117364
    Abstract: Haptic features are stored in a haptic device by preloading or otherwise downloading them, e.g., wirelessly, into the haptic device at the time of manufacture, immediately prior to game play, during game play, and/or at any other time. Haptic features may be activated, deactivated, modified or replaced at any time. All or a subset of the haptic features may be selected as an active play list, which may be modified as necessary. A host may manage some or all device memory and the haptic features stored therein. Haptic features stored in haptic devices and control information provided by the host are used by the haptic device to execute haptic effects. The haptic device may sustain haptic effects between control messages from the host. New communication messages may be added to an underlying communication protocol to support haptic effects. New messages may use header portions of communication packets as payload portions.

  • Patent number: 8099529
    Abstract: Systems and methods for performing native command queuing according to the protocol specified by Serial ATA II for transferring data between a disk and system memory are described. Native command queuing context for queued commands is maintained by a host controller device driver and is provided to the host controller as needed to process the queued commands. The host controller is simplified since it only stores the context of the one command being processed. The host controller generates a backoff interrupt when a command cannot be queued. The host controller generates a DMA transfer context request interrupt to request programming of the registers that store the context for the one command being processed.

  • Patent number: 8099584
    Abstract: Parallelism in a parallel processing subsystem is exploited in a scalable manner. A problem to be solved can be hierarchically decomposed into at least two levels of sub-problems. Individual threads of program execution are defined to solve the lowest-level sub-problems. The threads are grouped into one or more thread arrays, each of which solves a higher-level sub-problem. The thread arrays are executable by processing cores, each of which can execute at least one thread array at a time. Thread arrays can be grouped into grids of independent thread arrays, which solve still higher-level sub-problems or an entire problem. Thread arrays within a grid, or entire grids, can be distributed across all of the available processing cores as available in a particular system implementation.
