摘要:
A compact fluorescent lamp employs an inner exhaust tubulation formed from glass which is opaque to a given range of electromagnetic radiation. The exhaust tubulation is non-invasively sealed after an outer lamp envelope is sealed by directing upon the exhaust tubulation an amount of such radiation sufficient to heat the tubulation to its softening point. The outer envelope is transparent to the given radiation which, in a preferred embodiment, is in the range of 400 nm to 2500 nm.

Methods of rendering a view of a scene include steps that specify quality levels of anti-aliasing and texture filtering for predetermined regions of a display, or selected objects within the scene, or both. Methods of processing data for display include steps adapted to process portions of the image according to selected or predetermined anti-aliasing and texture filtering quality levels. Graphics processing equipment includes hardware or software adapted to perform non-uniform anti-aliasing of images according to specified criteria.

A method and apparatus provides context switching of logic in an integrated circuit using one or more test scan circuits that use test data during a test mode of operation of the integrated circuit to store and/or restore non-test data during normal operation of the integrated circuit. The integrated circuit includes context control logic operative to control the test scan circuit to at least one of: store and restore context state information contained in functional storage elements in response to detection of a request for a change in context during normal operation of the integrated circuit.

Command handling logic receives a plurality of command requests and groups the plurality of command requests into one of a plurality of command tracking classifications to produce classification tagged command requests. The plurality of classification tagged command requests and corresponding plurality of command responses are communicated via a bus. Command classification tracking logic tracks the plurality of classification tagged command requests and a corresponding plurality of classification tagged command response to determine when there are no outstanding command requests associated with one of the plurality of command tracking classifications. There are no outstanding command requests associated with one of the plurality of command tracking classifications when the command classification tracking logic has received a number of classification tagged command responses equal to the number of sent classification tagged command requests associated with the same command tracking classification.

A method, system, and computer program product are provided for controlling the blending of pixels using alpha values. The alpha value of a first pixel is compared to the alpha value of a second pixel. The results of the comparison are then used to choose a particular blending operation from among two or more possible blending operations that are made available. The chosen blending operation is then performed so as to produce a blended pixel. The output of the blending operation is referred to hereinafter as pixel display data and includes a set of color coordinates and an alpha value for the blended pixel. The pixel display data is then sent to a frame buffer.

Embodiments of a system and method for handling interrupts are described herein. In an embodiment interrupts from various client components in a system (also referred to as clients) are processed by an interrupt handler component uniformly. The various clients signal interrupts in different manners. For example, some clients signal interrupts in a level-based manner, and some clients signal interrupts in a pulse-based manner. In an embodiment, all interrupts received by the interrupt handler are formed into an event message according to a uniform format regardless of the manner in which the interrupt is signaled. The event message includes all information necessary for a host processor interrupt service routine (ISR) to service the interrupts without reading hardware registers. Event messages are stored in an event buffer for access and handling by the host. The event buffer is managed by the interrupt handler.

The invention described herein includes a system, method, and computer program product for adding functionality to an application program. The invention includes a tool which can be used in conjunction with any of a plurality of application programs. The tool can be represented to a user by a tool icon on a desktop. After creating or opening a file or other object with an application program, the user can drag and drop a tool icon representing the tool into the application window. This allows the tool program to operate on the object. A windowing system event handler receives information from a user interface regarding the dragging and dropping of the tool icon. The fact that the tool icon has been dragged and dropped into the application window is reported by the windowing system event handler to a base module. The base module mediates communication between the tool program and the application program. This allows the tool program to operate on the object, which may have been previously locked by the application program. Once the object has been unlocked, the tool can then operate on the object.

A system, method, and computer program product is presented for simulating a system of hardware components. Each component is simulated in a hardware definition language such as VERILOG. Each component is represented as a simulated device under test (DUT) that is incorporated into a simulation module. The invention synchronizes the simulation modules by issuing clock credit to each simulation module. Each simulation module can only operate when clock credit is available, and can only operate for some number of clock cycles corresponding to the value of the clock credit. Operation is said to consume the clock credit. After a simulation module has consumed its clock credit, its DUT halts. Once every simulation module has consumed its clock credit and halted, another clock credit can be issued. This allows checkpointing of the operation of each DUT and simulates parallelism of the DUTs using executable images of manageable size. A given DUT can include two or more subsets of logic that each require a clock signal having a different rate. Such subsets of the logic of a DUT are referred to as clock domains. The appropriate clock signals are created by a test bench component of the simulation module. The test bench creates a master clock signal for the DUT. The test bench then divides this clock signal to produce clock signals applied to the clock domains of the DUT. The test bench can be created through automated means by providing a system specification that defines the inputs (including clocks) and outputs of a DUT. This allows a test bench specific to the DUT to be created.
