Various embodiments are generally directed to techniques for controlling the use of locks that regulate access to shared resources by concurrently executed portions of code. An apparatus to control locking of a resource includes a processor component, a history analyzer for execution by the processor component to analyze at least one result of a replacement of a lock instruction of a first instance of code with a lock marker to allow the processor component to speculatively execute a second instance of code, and a locking component for execution by the processor component to replace the lock instruction with the lock marker based on analysis of the at least one result, the first and second instances of code to access a resource and the lock instruction to request a lock of access to the resource to the first instance of code. Other embodiments are described and claimed.

Techniques for controlling use of locks

Methods, data structures, instructions, and techniques for structured exception handling for user-level threads in a multi-threading system are provided. Registered filter routines may be dispatched to a thread unit not managed by the operating system (OS). The dispatch may occur by allowing an OS-managed thread unit (proxy) to invoke the OS-provided structured exception handling service (including dispatcher) on behalf of the sequestered thread unit. Alternatively, an OS-managed thread unit may include dispatch code and may, without OS intervention, dispatch the filter routine to the sequestered thread unit. Other embodiments are also described and claimed.

Structured exception handling for application-managed thread units

Data structure creation, organization and management techniques for data local to user-level threads are provided. In one embodiment, a method includes generating, for a user-level thread ('shred') to run on a thread unit that is not managed by an operating system ('OS'), a storage area for local data and maintaining state in the storage area across a context switch from the thread unit that is not managed by the OS to a second thread unit that is managed by the OS. Other embodiments are also described and claimed.

A method and apparatus are described for specifying arbitrary words in a rule-based grammar, such as a context-free grammar. A wildcard identifier is used in a context-free grammar file in place of a predefined category of words. Artificial phoneme combinations that represent generic words in a speech engine's vocabulary database, and that represent pronunciations of the predefined category of words are defined by rules. A speech engine uses the artificial phoneme combinations to determine acceptable words to listen to, and generates a results object comprising generic words corresponding to the artificial phoneme combinations, as well as non-generic words that do not exist in a given CFG, where the generic and non-generic words exist in the speech engine's vocabulary database. The word having the highest confidence level that is not a generic word is selected as the word most likely to have been spoken by the user.

Specifying arbitrary words in rule-based grammars

A speech recognition framework receives information about a recognized phrase from a speech engine. The framework identifies the application that is a focus of the recognized phrase. The framework then selects a handler function based on the recognized phrase and the application. The framework calls the handler function, which responds to the phrase.
