Abstract: Systems and methods for efficient thread arbitration in a processor. A processor comprises a multi-threaded resource. The resource may include an array of entries which may be allocated by threads. A thread arbitration table corresponding to a given thread stores a high and a low threshold value in each table entry. A thread history shift register (HSR) indexes the table, wherein each bit of the HSR indicates whether the given thread is a thread hog. When the given thread has more allocated entries in the array than the high threshold of the table entry, the given thread is stalled from further allocating array entries. Similarly, when the given thread has fewer allocated entries in the array than the low threshold of the selected table entry, the given thread is permitted to allocate entries. In this manner, threads that hog dynamic resources can be mitigated such that more resources are available to other threads that are not thread hogs.

Abstract: Methods and apparatus for rich image capture using focused plenoptic camera technology. A radiance camera employs focused plenoptic camera technology and includes sets of modulating elements that may be used to modulate the sampling of different aspects of the range of plenoptic data. The radiance camera, via the modulating elements, may capture a particular property of light, such as luminance, color, polarization, etc., differently in different microimages or in different portions of microimages. With the focused plenoptic camera technology, the microimages are captured at the same time in a single image. Thus, multiple microimages of the same image of a scene may be captured at different exposures, different colors, different polarities, and so on, in a single image at the same time. Captured images may be used, for example, in High Dynamic Range (HDR) imaging, spectral imaging, polarization imaging, 3D imaging, and other imaging applications.

Abstract: A physical computer system includes a processor and a memory configured to store instructions executable by the processor to implement a virtualization module, which in turn implements virtual machine(s) as a service on behalf of clients. Each virtual machine executes an operating system that is distinct from any underlying operating system executed by the physical computer system. The virtualization module instructs that the virtual machine(s) perform a computation that has been identified as a repeatable computation, to generate an original terminal state of the repeatable computation. In response to a request to repeat the repeatable computation, the virtualization module instructs that the virtual machine(s) perform the repeatable computation to generate a new terminal state of the repeatable computation, and, dependent upon a comparison of the original and new terminal states, to determine whether the repeatable computation has been successfully repeated according to a success criterion.

Abstract: Methods and apparatus for constraining solution space in image processing techniques may use the metadata for a set of images to constrain an image processing solution to a smaller solution space. In one embodiment, a process may require N parameters for processing an image. A determination may be made from metadata that multiple images were captured with the same camera/lens and with the same settings. A set of values may be estimated for the N parameters from data in one or more of the images. The process may then be applied to each of images using the set of values. In one embodiment, a value for a parameter of a process may be estimated for an image. If the estimated value deviates substantially from a value for the parameter in the metadata, the metadata value is used in the process instead of the estimated value.

Abstract: The present invention provides a preamble that is inserted into an OFDMA frame and has a common sequence for all the base stations participating in a transmission. The subscriber station performs fine synchronization using the common sequence on the common preamble, and the resulting peaks will provide the locations of candidate base stations. The base station specific search is then performed in the vicinities of those peaks by using base station specific pseudo-noise sequences. With this two stage cell search, the searching window is drastically reduced. The preamble is matched to known values by a respective receiver to decode the signals and permit multiple signals to be transferred from the transmitter to the receiver. The preamble may comprise two parts, Preamble-I and Preamble-2, which may be used in different systems, including multioutput, multi-input (MIMO) systems.

Abstract: A system and method is disclosed for verifying whether a test API of a high-security software platform implements a reference API when a verification tool has insufficient permissions to detect one or more members of the test API. A signature is determined for a reference API implementation, which includes multiple API members. Determining the signature involves identifying a proper subset of the API members, where the subset excludes one or more API members that are not programmatically detectable by a given verification tool executing on a high-security platform that implements the reference API. The member may not be detectable by the verification tool because the tool has insufficient permission to programmatically detect the member on the high-security platform. The signature is then configured to indicate the members of the subset and not the excluded members. The signature is then stored.

Each of the semi-transparent surfaces may be rendered to a first image buffer at a multi-sampled resolution. Each of the rendered semi-transparent surfaces at the multi-sampled resolution may be multiplied by one or more transparency values of one or more of the plurality of surfaces nearer than the rendered semi-transparent surface. Each of the rendered and attenuated semi-transparent surfaces may be reduced from the multi-sampled resolution to a display resolution and added at the display resolution to a second image buffer.

Abstract: The present invention allows transmission of multiple signals between masthead electronics and base housing electronics in a base station environment. At least some of the received signals from the multiple antennas are translated to being centered about different center frequencies, such that the translated signals may be combined into a composite signal including each of the received signals. The composite signal is then sent over a single feeder cable to base housing electronics, wherein the received signals are separated and processed by transceiver circuitry. Prior to being provided to the transceiver circuitry, those signals that were translated from being centered about one frequency to another may be retranslated to being centered about the original center frequency.

Abstract: In one embodiment, a processor comprises a memory management unit (MMU) and an interface unit coupled to the MMU and to an interface unit of the processor. The MMU comprises a queue configured to store pending hardware-generated page table entry (PTE) updates. The interface unit is configured to receive a synchronization operation on the interface that is defined to cause the pending hardware-generated PTE updates, if any, to be written to memory. The MMU is configured to accept a subsequent hardware-generated PTE update generated subsequent to receiving the synchronization operation even if the synchronization operation has not completed on the interface. In some embodiments, the MMU may accept the subsequent PTE update responsive to transmitting the pending PTE updates from the queue. In other embodiments, the pending PTE updates may be identified in the queue and subsequent updates may be received.

Abstract: Method and apparatus for the interactive enhancement of 2D art with 3D geometry. A surface inflation tool may be used to create a 3D shape by inflating the surface that interpolates the input boundaries. The surface inflation tool may, for example, obtain a closed 2D boundary as input, triangulate the area within the boundary to generate an initial surface, and inflate the surface while maintaining a fixed boundary. Using the mean curvature specified at boundary vertices as a degree of freedom, the tool may control the inflated surface efficiently using a single linear system. Embodiments handle both smooth and sharp position constraints. Position constraint vertices may also have curvature constraints specified for controlling the inflation of a local surface.

Abstract: Method and apparatus for modeling 3-D frustums using a single click-and-draw action. A cursor control device button is pressed at a desired starting point. The user then moves the cursor to draw a curve. When the curve intersects, the shape that has been drawn is saved as a start surface. When the cursor control device button is released, the method may search for one or more other intersections from the end of the curve. If another intersection is found, the intersection defines an end surface. If one or more additional intersections are found, the additional intersections may be used to define intermediate surfaces. The recorded points between the start and end surfaces define the path of the frustum. If a second intersection is not found, the start surface may be duplicated as the end surface. Once the user completes the curve, the frustum defined by the curve may be rendered.

Abstract: Techniques and structures are described which allow the detection of certain dependency conditions, including evil twin conditions, during the execution of computer instructions. Information used to detect dependencies may be stored in a logical map table, which may include a content-addressable memory. The logical map table may maintain a logical register to physical register mapping, including entries dedicated to physical registers available as rename registers. In one embodiment, each entry in the logical map table includes a first value usable to indicate whether only a portion of the physical register is valid and whether the physical register includes the most recent update to the logical register being renamed. Use of this first value may allow precise detection of dependency conditions, including evil twin conditions, upon an instruction reading from at least two portions of a logical register having an entry in the logical map table whose first value is set.
