摘要:
A serial input interface circuit includes a shift register connected to a data input terminal, a parallel register coupled via an output buffer to a data bus, a parallel register empty flag and a serial input suspension request flag which can be set, at any time during progress of input processing of input serial data into the shift register even while the parallel register empty flag is reset to indicate absence of parallel data in the parallel register and consequently even while the input serial data are supplied into the shift register, by a program for controlling transfer, to the data bus, of the parallel data which are stored in the parallel register when a predetermined transfer bit length of the input serial data is stored in the shift register. Setting of the serial input suspension request flag sets, in turn, a serial input suspension carry out flag immediately when the parallel register empty flag is reset. This prevents a serial input request signal generating circuit from producing a serial input request signal which would otherwise be produced to continue the input processing when the transfer bit length of the input serial data is stored in the shift register for delivery to the parallel register.

An image editor for editing image data of a document according to an attribute designated. The image editor includes attribute memory means for storing individual attributes for indicating a processing method of an image signal for every unit of a virtual area on an image area of a document, said virtual area being defined as one of the areas obtained by dividing the image area of a document regularly so as to have a larger area than that of one pixel and, attribute designation means for indicating an attribute of every unit of virtual area to said attribute memory means.

Storage systems and methods directed to tier management and tier movement. Tier management is conducted based on access frequency of data in a storage subsystem in comparison to the storage subsystem tier. The storage system may then manage cache pre-fetch or tier movement as file location granularity without a special management interface from the host to the storage system.

A vehicle turning efficiency improving apparatus is applicable to an automotive vehicle (20) of a type equipped with either a braking system (4L, 4R, etc.) or a driving train (6), which is capable of performing a braking force control or a driving force control separately on vehicle wheels (1L and 1R) and a steering unit (3) capable of steering the left and right vehicle wheels (1L and 1R) separately. A control unit (9) is provided for performing a turn assist control, in which a time difference is generated in steering operation of the left and right vehicle wheels (1L, 1R) and a braking/driving force difference is generated in the left and right vehicle wheels (1L, 1R) to thereby generate a yaw moment.

A virtual LU astride a plurality of storage devices is a virtual volume composed of a plurality of partial volumes. Functions of the storage system, Zoning information of a SAN and a host group information of the virtual volume are inherited to a partial volume created for each physical device. When a page granularity data migration is executed, volume or data are migrated to other storage devices without depending on the relationship between a physical port and the physical device. When a host IO request is received when migration is on-going, response processing is performed by synchronizing storage devices within the range of migration data. The host IO request related to the page being migrated sends a partial complete response including information for re-routing the request to a path of the appropriate data migration destination device capable of issuing the IO.

Data migration can be preformed between source and target storage subsystems without stopping exchanging data between a host computer and each of the storage subsystems.After a next access path, which should be set instead of a specific access path in an available state among access paths, is set between the host computer and a migration target logical unit via a host port and a target port, the status of the next access path is set to an available state and the status of the specific access path is set to an unavailable state. After the next access path is set to an available state, data is migrated from a migration source logical unit of the source storage subsystem to the migration target logical unit of the target storage subsystem.

The computer system of the present invention has a plurality of SAS target devices, an SAS initiator device, and a service delivery subsystem that is connected to each SAS target device by means of a physical link that is physical wiring and connected to the SAS initiator device by means of a wide link constituted by a plurality of physical links. The SAS initiator device controls how many physical links in the wide link are allocated to a particular SAS target device, whereby access from the SAS initiator device to the SAS target device is made via a physical link that is allocated to the SAS target device and is not made via a physical link that is not allocated to the SAS target device.

An image formation apparatus for performing a billing process, by generating billing information of a job after executing the job and transmitting the billing information to a billing apparatus when a connection to the billing apparatus is normal, the image formation apparatus comprising: a storage for storing therein billing information; a judgment part operable to judge whether the connection to the billing apparatus is normal (step S102); and a job execution controller operable to compare a size of billing information of a target job that is targeted for execution with a size of free space of the storage (step S109) in a case where the connection is judged to be a connection failure (No in step S102), and prohibit the execution of the target job (step S112) when the size of the billing information of the target job is larger than the size of the free space of the storage (No in step S109).
摘要:
An object of the present invention is to provide a means for detecting a logical command error, and a storage system and its control method that can properly perform error handling, and detection and blockage of a malfunctioning section. A storage control system includes controller units 130A and 130B for performing processing for data I/O to/from drives 150 and 160 in response to a data I/O request from a host device 100, switches 140A and 140B connecting the controller units 130A and 130B and the drives 150 and 160, and a port selector 300 inserted between the switches 140A and 140B and the drive 160. The port selector 300, when receiving a command generated based on processing performed by an MPU 131, accesses a target drive 160 if that data that forms a command is valid. Meanwhile, if the port selector 300 detects logical command inconsistency, the port selector 300 forwards that detection result to the MPU 131 via the switch 140A or 140B and requests retry processing from the MPU 131.
