摘要： A specific embodiment is disclosed for a method and apparatus for processing data access requests from a requesting device, such as a graphics processor device. Data access commands are provided at a first rate, for example 200M commands per second, to a memory bridge. In response to receiving the access requests the memory bridge will provide its own access requests to a plurality of memories at approximately the first rate. In response to the memory bridge requests, the plurality of memories will access a plurality of data at a second data rate. When the data access between the memory bridge and the memories is a read request, data is returned to the requesting device at a third data rate which is greater than the first data rate by approximately four-times or more. Noise and power reduction techniques can be used on the data bus between the accessing device and the data bridge.

摘要： A method and apparatus for space variant texture filtering begins when texture coordinates for a given pixel of an object being rendered are received. From the texture coordinates, first and second axis derivatives are determined. When the first and second axis derivatives have differing degrees of magnitude, a determination is made as to whether the first access derivative or the second axis derivative corresponds to a major axis. Next, a number of samples along the major axis are determined based on a logarithmic function of a ratio between the first and second derivatives. Having obtained the number of samples, a separation between the samples is determined based on derivatives along the major axis. Having obtained the number of samples and separation, one of a plurality of related texture maps (e.g., MIP maps) is referenced based on the derivatives along a minor access to obtain the samples. Having obtained the samples, they are filtered based on the number of samples to obtain a filtered texel for the given pixel.

摘要： In general, this disclosure describes techniques for providing a gesture-based user interface. For example, according to some aspects of the disclosure, a user interface generally includes a camera and a computing device that identifies and tracks the motion of one or more fingertips of a user. In some examples, the user interface is configured to identify predefined gestures (e.g., patterns of motion) associated with certain motions of the user's fingertips. In another example, the user interface is configured to identify hand postures (e.g., patterns of showing up of fingertips). Accordingly, the user can interact with the computing device by performing the gestures.

摘要： An image noise filter includes a wavelet transform module and an edge based adaptive filter module. The dual tree wavelet transform module provides low frequency wavelet information and high frequency wavelet information in response to image information. The edge based adaptive filter module provides filtered high frequency wavelet information in response to the high frequency wavelet information and edge information that is based on the low frequency wavelet information.

摘要： Described herein are methods, apparatus, and computer readable media to control a user interface on a remote control. A first device command may be received from a remote control. This device command may cause the device to leave a first functional mode and enter a second functional mode. A first remote control command may then be sent to the remote control, with the first remote control command identifying a first remote control user interface to be displayed. The user interface may be operative to control features of the device unique to the second functional mode.

摘要： To derive a Hamming code to manage data errors a set of at least four parity bit positions is selected for parity bits which will protect a set of data bits (where each data bit has a data bit position in the data bit set). A syndrome is determined for each data bit position. This involves selecting a unique sub-set of at least three parity bit positions. The unique sub-set shares at least one parity bit position with at least one other unique sub-set of at least three parity bit positions. A parity bit value may then be calculated for each parity bit position based on the determined syndromes. The header of a packet may be provided with a word which defines the length of the packet and an error management code generated utilizing this word so that errors in the word may be detected and, possibly, corrected.

摘要： A buffer is associated with each of a plurality of data lanes of a multi-lane serial data bus. Data words are timed through the buffers of active ones of the data lanes. Words timed through buffers of active data lanes are merged onto a parallel bus such that data words from each of the active data lanes are merged onto the parallel bus in a pre-defined repeating sequence of data lanes. This approach allows other, non-active, data lanes to remain in a power conservation state.

摘要： At least one illuminant white point estimate is determined in a color space having radially defined saturation based on a reference image. A chromatic adaptation correction vector (CACV) is determined based on the at least one illuminant white point estimate. Corrected pixels are obtained by applying the CACV (preferably in a cone response color space using a correction matrix based on the CACV) to uncorrected image pixels corresponding to a target image, which may comprise the reference image or another image.
