The ILFD control unit runs the injection locked frequency divider and sets a control parameter of the injection locked frequency divider based on each frequency of the reference signal and the frequency-divided signal measured in response to the control parameter of the injection locked frequency divider, in the stop state of the VCO.

Abstract: This invention provides an information search system including a management table which stores a name of a memory area and memory area information indicating the memory area in association with each other. When received source information search destination information indicates that source information to be searched is stored in a memory, the information search system searches the management table for a name of a memory area which matches a received source information name of the source information to be searched. When the name of the memory area which matches the received source information name of the source information to be searched is retrieved, the system acquires information which matches the received search target condition information from memory area information associated with the retrieved name of the memory area.

Abstract: An ILFD controller sets a control parameter on the basis of a frequency of a frequency-divided signal and a frequency of a reference signal measured by a clock counter. A VCO controller selects an oscillation band that defines an oscillation frequency of a VCO and also selects an oscillation band of the VCO on the basis of the frequency of the reference signal and a frequency of a frequency-divided signal that is a result obtained by frequency-dividing an output signal, which is delivered from the VCO in response to the selected oscillation band, by means of an ILFD and a frequency divider.

Abstract: An operation request from a process or OS for computer resource(s) managed by the OS, such as a file, network, storage device, display screen, or external device, is trapped before access to the computer resource. It is determined whether an access right for the computer resource designated by the trapped operation request is present. If the access right is present, the operation request is transferred to the operating system, and a result from the OS is returned to the request source process. If no access right is present, the operation request is denied, or the request is granted by charging in accordance with the contents of the computer resource.

Abstract: In a data conversion auxiliary module which is at a higher level than a file system in a disk management hierarchy, data stored in a storage medium, which becomes an object, is successively accessed. Then, a data conversion module captures a sector-unit access request to a device driver from the file system, converts data of a sector which is returned from the device driver, and writes the conversion data in the sector. Thereby, data conversion can be executed on a specific region of the storage medium, which is associated with the data in the storage medium.
