    摘要: A slave device (20), which is a communication device, receives and analyzes commands, and returns the results to a master device (10). During the command analysis period, an IIC control unit (205) and a CPU (210), which form a control unit, control an SCL control unit (201) so as to stop an SCL signal. When the value of a timer (206) is equal to or less than a threshold value, transmit data are saved in a transmission FIFO (203), control for stopping the SCL signal is canceled, and in synchronization with the SCL signal, an SDA control unit (202) transmits the data saved in the transmission FIFO (203) to the master device (10). When the value of the timer (206) exceeds the threshold value, control for stopping the SCL signal is canceled, the clock control unit is placed in a state to receive the clock signal, and the SDA control unit (202) is placed in a state to receive a slave address indicating a communication device that operates in the slave mode.

    摘要: An information processing device includes: a nonvolatile memory having a program area storing a program for booting a system, and backup areas each storing a backup program identical in content to the program; a process executing unit that executes the program to perform a boot process of the system; an error detection unit that performs error detection on the program in parallel with the boot process; and a reboot unit that, when the error detection unit detects an error in the program, performs a recovery process to replace the program with one of the backup programs, and reboots the system using the replaced program. In the recovery process, the reboot unit refers to history information indicating a history of replacement of the program with the backup programs, selects the backup program used for the replacement from among the backup programs, and replaces the program with the selected backup program.

    摘要: Each of image information playback units (11, 21) detects that image display has started, on the basis of a change in digital video data (VDa, VDb), and generates a frame number (FNa, FNb) (103, 203). One of the image information playback units (11) combines frame signals that output frame synchronization signals (FSa) (104). The other image information playback unit (21) separates the frame synchronization signals (FSa) and generates a frame number (SFNa) (205). The generated frame number (SFNa) and the frame number (FNb) generated in the second image information playback unit (21) are compared, and on the basis of the comparison results the frequency of the decoding reference clock signal is controlled (206). When images are displayed by a plurality of display units (15, 25) connected to the image information playback units (11, 21), the images can be synchronized with a simple structure.

    摘要: An information processing device including a reader unit connected through a connection switch to a first control section and a second control section. The first control section is connected to the connection switch by a first bus supporting a first specification. The second control section is connected to a conversion unit by a second bus supporting a second specification. The conversion unit is connected to the connection switch by a third bus supporting the first specification. When the connection switch connects the reader unit to the first control section, the second control section halts communication with the conversion unit, thereby avoiding unnecessary use of processing resources.
