Abstract: An invention is provided for rendering using an omnidirectional light. A shadow cube texture map having six cube faces centered by a light source is generated. Each cube face comprises a shadow texture having depth data from a perspective of the light source. In addition, each cube face is associated with an axis of a three-dimensional coordinate system. For each object fragment rendered from the camera's perspective a light-to-surface vector is defined from the light source to the object fragment, and particular texels within particular cube faces are selected based on the light-to-surface vector. The texel values are tested against a depth value computed from the light to surface vector. The object fragment is textured as in light or shadow according to the outcome of the test.

Abstract: Circuits, methods, and apparatus that reduce the power consumed by transactions initiated by a number of USB host controllers. Peripheral devices on a number of USB networks are accessed in a coordinated manner in order to reduce power dissipated by a CPU and other circuits when reading data needed by the host controllers. The resulting memory reads are temporally clustered. This allows the CPU to process a greater number of requests each time it leaves a low-power state. As a result, the CPU may possibly remain in a sleep state for a longer period of time, thus saving power. This is accomplished at the host controller level by synchronizing the time frames used by each host controller in a system. The synchronizing signal may be one or more bits of a frame count provided by one host controller to a number of other frame controllers.

Abstract: A basic block within a thread program is characterized for convergence based on mapping the basic block to an indicator subnet within a corresponding Petri net generated to model the thread program. Each block within the thread program may be similarly characterized. Each corresponding Petri net is enumerated to generate a corresponding state space graph. If the state space graph includes an exit node with an odd execution count attribute, such as by Petri net coloring, then the corresponding basic block is divergent. The corresponding basic block is convergent otherwise. Using this characterization technique, a thread program compiler may advantageously identify all convergent blocks within a thread program and apply appropriate optimizations to the convergent blocks.
