When a controller receives a command including random IO processing and the reception of commands is complete, it determines whether the valid extents prescribed in seek parameters attached to an LOC command overlap, and executes extent exclusive wait processing which causes access to the logical volume to enter a wait state or access processing to the logical volume based on the determination result. If the reception of commands is incomplete, the controller determines whether the access ranges (extents) designated in a DX command overlap, and executes extent exclusive wait processing or access processing to the logical volume based on the determination result.

    Abstract: A communication speed control application sets the initial communication mode of the USB controller to a full speed mode through a USB driver. If a data transfer start request is received from a USB device using application and if the requested communication speed is a high speed communication mode, the communication speed mode of the USB controller is changed to a high speed mode through the USB driver. The USB application estimates the transfer rate required for the data transfer to be executed and, if the estimated transfer rate is higher than the full speed mode or the transfer rate resulting from subtraction of a predetermined margin from the full speed, the requested communication speed is set to the high speed or is set to full speed otherwise.

    Abstract: An efficient transfer of data including a plurality of data sections is achieved. In a data transfer system including a first DMA 1142 of a channel control unit 11 and an MP 122 of a processor unit 12 that sets a transfer parameter in the first DMA 1142, while CKD format data 1400 is transferred from a cache memory 14 to a memory 113 of the channel control unit 11, the MP 122 acquires a C field 1411 from the cache memory 14 and sets a transfer parameter in the first DMA 1142 on the basis of the acquired C field 1411, the transfer parameter having attached thereto the C field 1411 and being used for transferring a K field 1412 from the cache memory 14 to the memory 113. The first DMA 1142 retrieves the C field 1411 attached to the transfer parameter, stores the C field 1411 in the memory 113, and transfers the K field from the cache memory 14 to the memory 113 according to the transfer parameter.

  • Patent number: 8112576
    Abstract: Methods, systems, and devices are described for the implementation of a novel architecture to support a calibrated rate for the transfer of circuit configuration data. Sets of configuration data from a memory may be transferred to volatile memory to support reconfigurable circuit elements, for example, for use in a clock generator. Upon system power-up, there may be a default speed for the transfer of the configuration data. Techniques are described to first transfer calibration data upon power-up; the transferred calibration data may then be used to set an accelerated speed for a remaining portion of the transfer.

  • Patent number: 8112554
    Abstract: A method of transmitting data on a data line between a central control device and a decentralized data processing device. During a normal operation of the system, the central control device periodically sends synchronization pulses to the at least one data processing device via the data line in order to request data packets, and the decentralized data processing device sends the data thereof to be transmitted, as data packets, to the central control device, following the synchronization pulse. The data line is embodied as a data bus. Each of the decentralized data processing devices is configured by the central control device before the first transmission of data packets to the central control device. In order to configure the system, a bi-directional communication is carried out between the central control device and the at least one decentralized data processing device.
