    摘要： A method and system are disclosed which allow a computer program to execute properly in object code compatible processing systems which have latencies different from those with which the program was created or compiled. This resulting compatibility of the computer program is achieved because the invention protects the precedence of operations within the computer program using latency assumptions which were used when creating the computer program. When the computer program is created, latency assumption information is efficiently provided within the computer program. Thereafter, when the computer program is executed, it is able to advise the processing system of the latency assumptions with which it was created. Various ways are described in which the processing system can utilize the latency assumptions when executing the computer program so as to ensure compatibility.

    摘要： Systems and methods of developing and/or implementing multimedia applications. The system provides an extensible framework including an application layer, a framework utility layer, and a core engine layer. The framework utility layer includes an application programming interface, a video codec sub-framework (XCF), a video packetization sub-framework (XPF), and a video/text overlay sub-framework (XOF). The core engine layer includes one or more core codec engines and one or more core rendering engines. The XCF, XPF, and XOF sub-frameworks are effectively decoupled from the multimedia applications executing on the application layer, and the core codec and rendering engines of the core engine layer, allowing the XCF, XPF, and XOF sub-frameworks and core codec/rendering engines to be independently extensible. The system also fosters enhanced reuse of existing multimedia applications across a plurality of multimedia systems.

    摘要： A CPU having a cluster VLIW architecture is shown which operates in both a high instruction level parallelism (ILP) mode and a low ILP mode. In high ILP mode, the CPU executes wide instruction words using all operational clusters of the CPU and all of a main instruction cache and main data cache of the CPU are accessible to a high ILP task. The CPU also includes a mini-instruction cache, a mini-instruction register and a mini-data cache which are inactive during high ILP mode. An instruction level controller in the CPU receives a low ILP signal, such as an interrupt or function call to a low ILP routine, and switches to low ILP mode. In low ILP mode, the main instruction cache and main data cache are deactivated to preserve their contents. At the same time, a predetermined cluster remains active while the remaining clusters are also deactivated. The low ILP task executes instructions from the mini-instruction cache which are input to the predetermined cluster through the mini-instruction register. The mini-data cache stores operands for the low ILP task. The separate mini-instruction cache and mini-data cache along with the use of only the predetermined cluster minimizes the pollution of the main instruction and data caches, as well as pollution of register files in the deactivated clusters, with regard to a task executing in high ILP mode.

    摘要： A mouthpiece through which a person may breathe has a sealing flange for introduction into the mouth. The sealing flange has an upper portion for lying against the hard palate and a lower portion for fitting between the lower lip and the anterior surface about the lower teeth and gums. The juxtaposition in the mouth of the upper portion against the hard palate and the lower portion seated in the lower vestibule portion of the mouth results in the sealing flange forming an effective seal and the sealing flange being comfortably held in place in the mouth even when the mouth is open to the extent of the normal relaxed muscle tone of the mouth. To facilitate the seal when the mouthpiece is introduced into the mouth, a tooth tray is provided. Another aspect of the invention permits the mouthpiece to envelop the nostrils such that when the mouthpiece is in place all inspired and expired air must pass through the mouthpiece. In the best embodiment of the invention, the nostrils are enveloped by a naso-labial hood which envelops the entire nose forming a seal against the outline of the nose, thereby minimizing the non-respiratory tract dead air space inside the volume of the naso-labial hood.

    摘要： Methods apparatus for storing and expanding wide instruction words in a computer system are provided. The computer system includes a memory and an instruction cache. Compressed instruction words of a program are stored in a code heap segment of the memory, and code pointers are stored in a code pointer segment of the memory. Each of the code pointers contains a pointer to one of the compressed instruction words. Part of the program is stored in the instruction cache as expanded instruction words. During execution of the program, an instruction word is accessed in the instruction cache. When the instruction word required for execution is not present in the instruction cache, thereby indicating a cache miss, a code pointer corresponding to the required instruction word is accessed in the code pointer segment of memory. The code pointer is used to access a compressed instruction word corresponding to the required instruction word in the code heap segment of memory. The compressed instruction word is expanded to provide an expanded instruction word, which is loaded into the instruction cache and is accessed for execution.
