  • Patent number: 8803905
    Abstract: A display control device includes: a transparent color information storage unit that stores transparent color information; a run-length counter that calculates a run-length specifying the number of consecutive pixels having the same color information; a combination calculation unit that combines the image data for the plurality of display layers; and a combined image display unit that outputs the combined image data to a display device. If the color information for a total of run-length pixels calculated by the run-length counter is a transparent color, the combination calculation unit performs combination by ignoring the image data for the total number run-length of consecutive pixels.

  • Publication number: 20110265093
    Abstract: A computer system includes a plurality of processors, a shared resource being used by the processors, and a storage unit in which management information corresponding to the shared resource is stored. The management information includes a semaphore for each OS managing a task which runs on the processors, a queue in which information for specifying a processor which has requested acquisition of the shared resource is stored in series, and a resource counter indicating a remaining number of the shared resources which can be acquired. Each of the processors includes a counter obtaining section that obtains a value of the resource counter, an acquisition decision-making section that makes a decision as to whether or not the shared resource can be acquired, and a resource acquiring section that stores information for specifying the processor in the queue if decided that it can not be acquired.

  • Patent number: 7502674
    Abstract: In an on-vehicle terminal system operating a plurality of operating systems, control of peripheral devices connected to the on-vehicle terminal system can be continued even if one of the operating systems is stopped. A second operating system monitors an operating status of a first operating system using an OS status monitoring function. When the first operating system stops, a list recording allocation of the peripheral devices is updated to switch the allocation to the second operating system. By doing so, an interrupt signal from a peripheral device is allocated to the second operating system, and accordingly the second operating system can control the peripheral device.

  • Publication number: 20060130000
    Abstract: If a plurality of operating systems are running in one computer and each of those operating systems has its own managed time, which is different from others, then trace log information items collected by those operating systems and merged in order of their generated times may not be as they are generated actually. In order to avoid such a problem, therefore, the present invention provides an operating system management system with recording means for storing a check point trace in the operation trace information of each of those operating systems, thereby finding the correspondence among those check point traces by searching the operation trace information item of each operating system, then adding such additional information as a time difference, a counter value, etc. to the operation trace information.
