Abstract: An updating and reference management system with an area management unit and a timing unit for a shared memory. Processes access the shared memory in an identical time frame, determined by the timing unit, such that update or reference requests by the processes for the shared memory are held by the area management unit in each time interval between control signals generated by the timing unit. The update or reference requests are executed at the time of each control signal. Processing objects manage the update or reference requests for respective portions of the shared memory. The managing objects for the shared memory also pre-process potentially conflicting update requests to the same portions of the shared memory such that the shared memory is updated with different data, determined to be appropriate by the respective managing object.

Abstract: A semantic recognition system of the present invention provides a user interface capable of receiving speech input to a user and an application interface that conveys an input content of the user to an application. The semantic recognition system includes a speech signal input part for receiving input speech signals, a speech recognizer for recognizing a corresponding word based on the input speech signals, a recognized word-semantic number converter including a semantic number-registered word list indicating the correspondence between a semantic number representing a meaning of a word and a registered word belonging to the semantic number, an application interface and an application handling the semantic numbers as data. The corresponding word is recognized by the speech recognizer, based on the speech signals input to the speech signal input part. The recognized word is converted to a corresponding semantic number by the recognized word-semantic number converter.

Abstract: There is provided a periodic process load control system for controlling a load of a CPU in conjunction with an execution of a periodic process in a multiple-process operating system having the CPU in which a plurality of processes including a periodic process activated periodically are executed on a time division basis, and a periodic process recording medium for storing a periodic process into which such a load control function is incorporated. A time interval in which the periodic process is repeatedly executed is measured to evaluate a load evaluation value consisting of an accumulation value of the time intervals. A load of the periodic process itself is controlled in accordance with the load evaluation value.

Abstract: A synchronous control apparatus comprising a trigger signal generating unit periodically generating a trigger signal, plural modules executing plural processes which are to be synchronized with each other, respectively, and a module control unit 31 sequentially starting the plural modules once according to a predetermined execution order, where the module control unit 31 sequentially starts the plural modules once according to the execution order each time the trigger signal is input, so that precise synchronization of the modules is achieved. As a result, synchronously controlling plural modules which can be executed independently from each other, specifically in generating animated images in real time, movements of characters and objects displayed on a screen can be precisely synchronized with each other.

Abstract: The present invention relates to a time management system for a memory for processing a time-series data, such as animation image and a sound data. The time-series data is managed on a timewise basis so that it is possible to transfer the time-series data into a real memory without a swap-out/swap-in operation. The present invention includes a memory unit 5, a time measuring unit 3 including a time managing table 31 to manage a timing for acquisition/release of an area in the memory unit, and an area managing unit 4 including a user area time managing table 41 to manage the memory unit on a timewise basis in accordance with an area acquisition signal and an area release signal transferred from the time measuring unit. When the time measuring unit 3 detects a designated time, it requests an acquisition of the memory unit from the area managing unit 4, and when the time measuring unit 3 detects a time-out of the designated time, it sends a release of the memory unit request to the area managing unit 4.

Abstract: A multi-media scheduling system for scheduling multi-media applications which include media having priorities based on time restrictions. The multi-media scheduling system includes a managing unit for managing requests of each of the media of the multi-media applications, a sorter for rearranging the requests managed by the managing unit in a sequence starting from a request having a strongest time restriction, and a preemptive scheduler for scheduling the rearranged requests in the managing unit by reducing priority of at least one request which has a predetermined priority information lower than a predetermined value if the time restriction of the media prevents desired scheduling, where the predetermined priority information is selected from at least a group of information consisting of a quality which indicates a tolerance of a delay from a request time of each request and an importance which indicates an importance of each request.

Abstract: A switching system for application services is provided with a terminal. At least one application processor stores a plurality of application programs for providing a plurality of the application services. Switching equipment couples the terminal to the application processor. The terminal has a specifying means for specifying one arbitrary application service out of the plurality of application services. When a user specifies the one arbitrary application service using the specifying means of the terminal, this information is transmitted to a common control unit of the switching equipment. The common control unit receives the application service specifying information from the terminal, and transfers this application specifying information to the application processor. The application processor selects the one arbitrary application service based on the application service specifying information which is transferred from the switching equipment.
