Abstract: A multi-lingual indexing and search system performs tokenization and stemming in a manner which is independent of whether index entries and search terms appear as words in a dictionary. During the tokenization phase of the process, a string of text is separated into individual word tokens, and predetermined types of tokens are eliminated from further processing. The stemming phase of the process reduces words to grammatical stems by removing known word-endings associated with the various languages to be supported. Known word endings are removed from the word tokens without any effort to guarantee that the remaining stem is contained in a dictionary. In a preferred implementation, the stemming process is only applied to nouns.

Abstract: Apparatus and techniques for awakening bus circuitry from an inactive state as needed are described. The bus circuitry forms part of a computer system and is placed in the inactive state (i.e., shut down) when not needed so as to conserve power. The bus circuitry is associated with a bus and can be awakened out of the inactive state when certain bus events, including resume, connect or disconnect, occur on the bus. The invention is particularly advantageous for computing devices (e.g., portable computers, desktop computers, server computers) where it is desirous to shut down bus circuitry as well as other circuitry (e.g., microprocessor) when not needed so as to reduce power consumption.

Abstract: A method and an apparatus for improved duration modeling of phonemes in a speech synthesis system are provided. According to one aspect, text is received into a processor of a speech synthesis system. The received text is processed using a sum-of-products phoneme duration model that is used in either the formant method or the concatenative method of speech generation. The phoneme duration model, which is used along with a phoneme pitch model, is produced by developing a non-exponential functional transformation form for use with a generalized additive model. The non-exponential functional transformation form comprises a root sinusoidal transformation that is controlled in response to a minimum phoneme duration and a maximum phoneme duration. The minimum and maximum phoneme durations are observed in training data. The received text is processed by specifying at least one of a number of contextual factors for the generalized additive model.

Abstract: A DVD authoring system in a processor-based system removes an author from consideration of the DVD Specification during authoring. According to a preferred embodiment, the authoring system provides an authoring engine having an interactive graphical authoring interface, a data management engine, an emulator, a compiler, a multiplexer and a simulator. Using summary authoring data, the compiler builds a skeleton-form PGC layout structure comprising control PGC abstractions and router PGC abstractions. The compiler then resolves the PGC abstractions according to source-target connections. During playback on a DVD player, the PGC abstractions form elements in a connection-switching abstraction superstructure. Accordingly, in response to DVD-consumer and other control events, a source PGC preferably determines target PGC information and then transfers control, via virtual connections through necessary router PGC abstractions, to a target PGC abstraction.

Abstract: A method and apparatus for distinguishing reference values from non-reference values in a runtime environment is described. A set of volatile registers and a set of non-volatile registers are statically determined. The set of volatile registers is partitioned into reference and non-reference register partitions statically. The set of non-volatile registers is partitioned into reference and non-reference partitions dynamically.

Abstract: A system and method is described which provides for context checking of an operating environment. A context manager controls the execution of context checks requested by applications or processes. In one embodiment, the context check modules are defined as self-contained modules located in a database. When the data base is opened, these modules are loaded and registered with the context manager. Upon occurrence of certain user actions, the context manager will issue an event to cause the appropriate modules to perform a context check of certain context of the environment. The resulting context information is stored in memory by the context manager and provided to the applications by the context manager when needed. One advantage is that the context checks performed can be changed simply by adding or deleting modules from the database.

Abstract: A method and apparatus are provided for performing need based synchronization of a time clock maintained by a computer system. A number of computer systems are connected to a network, such as the Internet. Each computer system synchronizes its time clock by accessing a time server via the network. The time server may service a large number of client computer systems for purposes of providing accurate time of day readings and may therefore be subject to substantial loading. Accordingly, in each client system, the time clock is synchronized at least twice, and an amount of drift in the time clock is determined based on the two or more synchronizations. The synchronization interval for future synchronizations of the clock or the specific time of the next synchronization is then determined based upon the amount of drift, such that the time clock of each client computer system is synchronized only when necessary, and such that the loading on the time server is reduced.

Abstract: An arbiter arbitrates between PCI agents within an ASIC. The ASIC interfaces with an external PCI bus. In operation, the arbiter receives request signals from the PCI agents, and in response thereto, generates a single external request signal. Once the grant is received by the ASIC, the arbiter will route it to a selected PCI agent. The selected agent then gains access to the PCI bus and all other agents are locked out until the transaction is completed. The arbiter is implemented in such a way that there is a minium delay between the generation of the request by any agent and the request sent out by the ASIC. This is performed by ORing all requests.

Abstract: A lookup operation is carried out on a data table by logically dividing the data table into a number of smaller sets of data that can be indexed with a single byte of data. Each set of data consists of two vectors, which constitute the operands for a permute instruction. Only a limited number of bits are required to index into the table during the execution of this instruction. The remaining bits of each index are used as masks into a series of select instructions. The select instruction chooses between two vector components, based on the mask, and places the selected components into a new vector. The mask is generated by shifting one of the higher order bits of the index to the most significant position, and then propagating that bit throughout a byte, for example by means of an arithmetic shift. This procedure is carried out for all of the index bytes in the vector, to generate a select mask.
