A display apparatus includes a plurality of surfaces, and a display device provided on at least one surface among the plurality of surfaces. A plurality of communication sections are arranged to correspond to at least two or more side surfaces with respect to the surface on which the display device is provided among the plurality of surfaces and configured to perform communication within a predetermined distance, each of the plurality of communication sections including different identification information. A control section is configured to perform control of the plurality of communication sections and the display device. When another display apparatus is connected to the display apparatus, the control section periodically performs time synchronization to synchronize an image displayed on the display device with an image displayed on a display device provided in the other display apparatus.

Display apparatus and display system

According to an embodiment, a display block is a display apparatus including a plurality of surfaces. The display block includes a display device, a plurality of transmitting/receiving sections that perform communication within a predetermined distance, and a control section. The display device is provided on at least one surface of the plurality of surfaces. The plurality of transmitting/receiving sections are arranged to correspond to at least two or more side surfaces with respect to the surface on which the display device is provided among the plurality of surfaces. The control section performs control of the plurality of transmitting/receiving sections and the display device.

According to one embodiment, an interface control apparatus includes an interface, a table, a command processor, and a controller. The interface transmits and receives information to and from a host. The table holds management information for managing an address in a memory space in the host. The command processor carries out a command process of accessing the memory space in the host using the management information. The controller releases the management information corresponding to the command process from the table in response to completion of the command process.

Interface control apparatus, data storage apparatus and interface control method

According to one embodiment, an interface control apparatus includes an interface, and a controller. The interface is configured to transmit information between a host and a data storage apparatus. The controller is configured to fetch request information making a processing request for the data storage apparatus, from an element being a storage unit of a queue provided on the host through the interface. The controller is configured to execute read request processing of fetching first request information divided into a plurality of elements and stored, with priority over second request information which is different from the first request information, when the request information is fetched.

Firmware FWand FWis separately stored in a non-volatile memory, in which a boot code for start-up and a restoration code are stored, and a first magnetic disk. A copy of the firmware FWstored in the non-volatile memory is stored in the first magnetic disk, and a copy of the entire firmware FWand FWstored in the first disk medium is stored in the second magnetic disk. When an error occurs during firmware update, upon next power-on, whether the volatile memory, the first magnetic disk, and the second magnetic disk are normal or abnormal is determined, and valid firmware is read and allocated to the volatile memory so as to perform start-up by a start-up mode corresponding to the determination contents.

In a radio apparatus, the band of a loop filter of a synthesizer in a blank channel searching state is narrower than the band in a communicating state. In addition, a radio wave environment is measured. A characteristic necessary for the radio apparatus is determined corresponding to the measured-radio wave environment. The power is controlled corresponding to the performance of the radio apparatus. Thus, the power consumption is decreased. In addition, the efficiency of the output power is improved. In the radio apparatus, the current consumption of a power amplifier PA is measured. A matching circuit (LNA or MIX) of the antenna is adjusted with the measured result so as to decrease an antenna loss. In the radio apparatus, a DC offset is removed from the transmitted power and the reflected wave. When the DC offset is removed using an AC coupling capacitor, the deterioration of the frequency characteristic of the receiving portion is compensated with a capacitor in a digital signal process. In the radio apparatus, a transmission power detecting portion is structured as an IC chip. The transmission power detecting portion detects the transmission power corresponding to leakage currents in the power supply of the IC chip and the ground. Thus, when the power is detected, a power loss is suppressed. Consequently, the power consumption of the radio apparatus can be decreased.
