Abstract: A command conversion device 14 is connected between an amplifier device 11 and a portable player 13. The amplifier device 11 sends/receives a plurality of types of first commands corresponding to a plurality of types of devices (e.g., CD players, MD recorders, tape recorders, etc.), and performs an operation based on a received first command. The portable player 13 sends/receives a second command, and performs an operation based on a received second command. The command conversion device 14 includes a selector for selecting a type of a first command, and a converter. When a first command of the type selected by the selector is received from the amplifier device 11, the converter converts the received first command into a second command, and sends the second command to the portable player 13.

Abstract: A hardware-based offload engine is disclosed for mapping protected data into frames. For a write operation, the HBA determines host addresses and the size of data to be read from those addresses. The HBA also determines the frame size and protection scheme for data to be written. A frame transmit engine reads each host descriptor in the host data descriptor list to determine the location and byte count of the data to be read. A DMA engine reads the protection information/scratch area to determine the exact data size used to fill each frame and the protection scheme, and retrieves one or more free frame buffers. Check bytes are inserted alongside the data and stored in free frame buffers. After each frame is filled, the frame transmit engine also generates and stores header information for that frame, and then combines header, data and check bytes for transmission over the network.

Abstract: The present invention provides a virtual machine system and a method of accessing a graphics card. The virtual machine system includes a VMM, an SOS and at least one GOS, and further includes a resource converting module for performing IO address converting on graphics card framebuffer accessing data from GOS(s) or mapping MMIO(s) to physical MMIO(s) of a graphics card based on a resource converting table, and sending the processed data to the graphics card; and a framebuffer allocating module for dividing a framebuffer resource of the graphics card into multiple blocks and allocating them respectively to corresponding GOS(s). The resource converting table(s) records correspondences between a resource allocation for the graphics card by SOS and a resource allocation for the graphics card by GOS(s). The framebuffer MMIO resource(s) allocated to the graphics card by GOS(s) is/are the framebuffer allocated to GOS(s) by the framebuffer allocating module.

Abstract: An acquisition condition of information can automatically be determined based on data processed by a multi-function peripheral to acquire information from other multi-function peripherals in accordance with the condition while maintaining security. When an MFP performs a printing process or an image reading process by scanner in a system connecting a plurality of MFPs, a certain predetermined word and the number of usage times thereof, etc., are extracted from the data and written and retained into log information. The MFP determines whether associated data are acquired from other MFPs for each word extracted based on the log information. If a certain MFP acquires data processed by other MFPs, the log information retained by other MFPs is checked in accordance with an acquisition condition retained by each MFP, and data corresponding to the log information conforming to the acquisition condition are acquired from other MFPs and stored in the own machine.

Abstract: The present invention relates to a system and methodology to facilitate I/O access to a computer storage medium in a predictable and efficient manner. A scheduling system is provided that mitigates the problem of providing differing levels of performance guarantees for disk I/O in view of varying levels of data access requirements. In one aspect, the scheduling system includes an algorithm or component that provides high performance I/O updates while maintaining high throughput to the disk in a bounded or determined manner. This is achieved by dynamically balancing considerations of I/O access time and latency with considerations of data scheduling requirements. Also, the system provides latency boundaries for multimedia applications as well as managing accesses for other applications.

The method of transferring data includes the steps of writing data from a controller to a volatile memory, placing the volatile memory in a transfer state, transferring the data from the volatile memory in the transfer state to a nonvolatile memory, and releasing the volatile memory from the transfer state in response to confirming completion of the transfer of the data.

Abstract: System and method for performing distributed input/output (I/O). A distributed I/O device (the device) coupled to a controller may read data from a serial port, may determine if the data are framed by time, and if so, may handle the data according to a time-based protocol. If the data are not framed by time, the device may determine if the data are framed by delimiters, and if so, may determine an appropriate delimiter-based protocol for the data from a plurality of delimiter-based protocols, and handle the data according to the appropriate delimiter-based protocol. This process may be repeated in an iterative manner to read a stream of data from the serial port. The device may include or be coupled to one or more I/O modules (e.g., for DAQ, motion control, etc.), which themselves may be coupled to a unit under test or other external device or phenomenon via additional devices.

Abstract: A system and method for interrupt processing includes a technique for exiting from interrupt mode in multiple processor systems. Those processors that were in a suspended or halt state immediately before entering the interrupt mode are released immediately with reference to the resolution of the interrupt condition. Those processors not responsible for the processing tasks associated with resolving the interrupt condition serially exit from interrupt mode on a time-delayed basis following the resolution of the interrupt condition.

Abstract: Methods, systems and apparatus for suppressing redundancy in data transmission over networks are provided. Data segments are transmitted from a transmitting DPU to a receiving DPU. Initially, only signatures of the transmitted data segments are stored in a cache at the transmitting DPU. A data segment is stored in the cache only if it satisfies a redundancy-suppressing admission policy. Such a data segment is referred to as a redundant data segment. The redundant data segment is also stored in a cache at the receiving DPU. The transmitting DPU transmits the signatures of the redundant data segments to the receiving DPU, which then extracts the redundant data segments from its cache. Therefore, transmission of the redundant data segments is suppressed.

Abstract: A buffer includes a plurality of serial inputs, a plurality of de-serializers, each coupled to a respective input, a plurality n of buffers and a media access controller having inputs coupled to the plurality of de-serializers, data outputs coupled to the buffers, and two control outputs coupled to respective buffers for buffering input data at a clock rate one-nth that of the input data. Preferably the buffer is a bifurcate buffer. In operation, serial packets are received on a port. They must be converted to parallel data for processing by conventional CMOS logic, however there are limits serial to parallel conversion ratio. This buffer describe circumvents theses limits.

Abstract: A target discovery manager associated with a target discovery layer is interposed between a host initiator and one or more discovery protocols. The target discovery manager maintains a list of target devices found by each of several target discovery protocols. For each discovered target device listed, the associated discovery protocols that discovered the target device are prioritized and coalesced into a single enumerated target device register. The target device register provides the host initiator with a single list of known target devices produced from multiple discovery protocols with the discovery protocols that independently discovered each device prioritized according to various parameters.
