Abstract: A method for deinterlacing video includes constructing a temporary frame of deinterlaced video based on a first (i.e., current) field of interlaced video, wherein the temporary frame includes pixels in lines of the temporary frame associated with the first field of interlaced video, placeholder pixels in identified areas of motion in lines of the frame associated with a missing field of interlaced video, and pixels from an opposite field of polarity of interlaced video in areas without motion. The method further includes replacing the placeholder pixels in the identified areas of motion with pixels interpolated using an edge direction interpolation scheme based on pixels in the first field of interlaced video, resulting in a reconstructed frame. In one example, a motion adaptive interpolator may construct the temporary frame, and an edge directional interpolator may generate the reconstructed/deinterlaced the frame.

Abstract: The embodiments of the present invention are a method and apparatus to perform anti-aliasing using multi-sampling on a non-power-of-two pixel grid. Using the present invention with 6 sample multisampling gives the same visual antialiasing quality as 8 samples using a prior art technique but uses less memory. A non-power-of-two equally spaced sample from a conventional grid of size N×N, where N is 12 can be chosen using the present invention. A scan conversion to determine the set of pixels covered by a polygon is performed in two parts. According to one embodiment, the present invention can multiply and divide by “N” in order to multisample an image using samples per pixel chosen from a N×N sub-sample grid, where “N” is not necessarily a power of 2. The present invention performs the divide by “N” step, where the step is achieved using a quick divide by 3 or 12 technique.

Abstract: A SIMD processor responds to a single min/max instruction to find the minimum or maximum valued data unit in an array of data units. The determined minimum/maximum value and an associated index value thereto may be output. Alternatively, the value of a data unit in another array may be output at a corresponding location. A further single instruction executable by the SIMD processor, may be applied to results obtained using such a single min/max instruction, to allow such instructions to operate on two dimensional arrays.

Abstract: A differential serial communication receiver circuit automatically compensates for intrapair skew between received differential signals on a serial differential communication link, with deterministic skew adjustment set during a receiver training period. Intrapair skew refers to the skew within a pair of differential signals, and is hence interchangeable with the term differential skew in the context of this document. During the receiver training period, a training data pattern is received, such as alternating ones and zeros (e.g., a D10.2 pattern as is known in the art), rather than an actual data payload. The differential serial communication receiver circuit includes a differential skew compensation circuit to compensate for intrapair skew.

The switch control biasing circuit provides a switch control biasing voltage to control a state of the switch based on a voltage level of the output. Further, a bulk biasing circuit is included and operatively coupled to the switch. The bulk biasing circuit selectively provides a bulk biasing voltage to the switch based on the voltage level of the output.

Abstract: An efficient method for improving use of different fill modes in vector graphics and a system using the method. The filling method uses a graphics hardware that is capable of producing objects to be filled. Before the actual filling the edges of the objects must be computed. Edges are then stored into an edge buffer. The buffer may be a separate buffer block or a pointer to a memory. The edge buffer comprises only the edges of the object to be rendered. When the object is actually is rendered, rendering function is called with at least one parameter. The parameters include the fill mode with which the object is rendered to the screen.

Abstract: A frame construction engine constructs a first frame of deinterlaced video and a second frame of deinterlaced video based on a first field of interlaced video and based on a second field of interlaced video, independent of any other fields of interlaced video. The frame construction engine constructs the first frame of deinterlaced video by assigning pixel values from the first field of interlaced video to corresponding pixel locations in the first frame. The frame construction engine constructs the second frame of deinterlaced video by assigning pixel values from the second field of interlaced video to corresponding pixel locations in the second frame. Missing pixel locations in each of the frames are selected from a corresponding field of spatially interpolated pixel values or from an opposite field of deinterlaced video.

Abstract: An upscaler is disclosed that upscales each of a maximum value map, a minimum value map and an average value map to a destination resolution. A blending module generates a detail-enhanced upscaled image of the source image having the destination resolution by blending corresponding pixel values from an upscaled image of the source image with at least one of: the upscaled maximum value map and the upscaled minimum value map. The blending may be based on the strength of detected edges in the source image and further based on a comparison of each pixel value in the upscaled image with a corresponding pixel value in an average value map. A source image characteristic calculator may generate the maximum value map, the minimum value map and the average value map based on the intensity values of a source image.

Abstract: A technique for approximating output values of a function based on LaGrange polynomials is provided. Factorization of a LaGrange polynomial results in a simplified representation of the LaGrange polynomial. With this simplified representation, an output value of a function may be determined based on an input value comprising a fixed point input mantissa and an input exponent. Based on a first portion of the fixed point input mantissa, a point value and at least one slope value are provided. At least one slope value is based on a LaGrange polynomial approximation of the function. Thereafter, the point value and the at least one slope value are combined with a second portion of the fixed point input mantissa to provide an output mantissa. Based on this technique, a single set of relatively simple hardware elements may be used to implement a variety of functions with high precision.
