Abstract: A method and apparatus for controlling power consumption in a multi-threaded processor. In one embodiment, the processor includes at least one logic unit for processing instructions. The logic unit includes a plurality of positions, wherein each of the plurality of positions corresponds to at least one instruction thread. Clock signals may be provided to the logic unit via a clock gating unit. The clock gating unit is configured to inhibit a clock signal from being provided to a corresponding one of the thread positions when no instruction thread is active for that position. The inhibiting of the clock signal for an inactive thread position may reduce power consumption by the processor.

Abstract: A graphics system configured with a scheduling network, a sample buffer, a rendering engine and a filtering engine. The rendering engine is configured to generate samples in response to received graphics data, and to forward the samples to the scheduling network for storage in the sample buffer. The filtering engine is configured to send a request for samples to the scheduling network. The scheduling network is configured to compare a video set designation of the request to a previous request designation, to update one or more state registers in one or more memory devices of the sample buffer in response to a determination that the video set designation of the request is different from the previous request designation, and to assert signals inducing a transfer of a collection of samples corresponding to the request from the one or more memory devices to the filtering engine.

Abstract: A system and method that manages scene graphs by data staging is contemplated. Data staging entails selectively loading only the portions of the scene graph that are currently needed or likely to be needed in the near future. Other objects in the scene graph that are not currently needed or likely to be needed may be replaced by pointers. The pointers may point to the location from which the objects may be accessed if necessary for a future frame. The replaced portions of the scene graph may be compressed and/or cached to a local memory device (e.g., a local array of read-write optical drives) capable of storing large amounts of data, with the pointers indicating where the objects are stored.

Abstract: A three-tiered data caching system is used on a distributed computer system comprising hosts connected by a network. The lowest tier comprises management facade software running on each machine that converts a platform-dependent interface written with low-level kernel routines that actually implement the data caching system to platform-independent method calls. The middle tier is a set of federated Java beans that communicate with each other, with the management facades and with the upper tier of the system. The upper tier of the inventive system comprises presentation programs that can be directly manipulated by management personnel to view and control the system. In one embodiment, the federated Java beans can run on any machine in the system and communicate, via the network. A data caching management facade runs on selected hosts and at least one data caching bean also runs on those hosts.

Abstract: A set of computer code is profiled by breaking each code segment of the computer code down into basic instructions. Thereafter, the set of computer code is executed. As each code segment is executed, a log is updated to indicate execution of that code segment. This is done for each executed code segment; thus, at the end of execution, the log reflects all of the code segments that were executed, and how many times each code segment was executed. Using the log, and a set of calibration statistics, which specify how much processing time is consumed by each basic instruction, an overall execution cost is derived for each executed code segment. The set of overall execution costs for all of the executed code segments are incorporated into an overall profile for the set of computer code.

A first application is executed by the first harness client and according to the test script. The first application outputs data to a central location. The output data can be monitored and the execution of first application controlled according to the output data.

A hardware component to be bound with a platform, a platform identity module, and a system for binding a hardware component and a platform also are described.

Abstract: Methods and systems for administratively qualifying and disqualifying test programs of a suite as excludable from performance by a client are disclosed in conjunction with a test framework. Using a graphical user interface that represents the suite as a hierarchy or tree, an administrator is able to select test programs or entire divisions of a tree in order to disqualify these elements from exclusion by clients. The results of the operation are compactly stored in a table of excludable records, as pointers to a node of the tree, rather than individual elements of the subtree headed by the node. Using the same graphical user interface, the client is allowed to see only those elements of the tree that have not been disqualified by the administrator. The client can select visible elements of the tree to prevent one or more test programs of the suite from being executed.

The at least one content provider includes an applet provider, a device manufacturer, a device issuer, and a trusted post-issuance installer. The content includes at least one program unit, where each program unit comprises an Application Programming Interface (API) definition file and an implementation.
