    • Transfer functions are often used for image processing. Look-up tables can be used to implement transfer functions in a processor-efficient manner. In one embodiment, the invention is an apparatus that includes a look-up table (LUT) storing sample outputs from an output range of a transfer function, the sample outputs corresponding to sample inputs from an input range of the transfer function, the sample inputs being distributed so that more sample inputs are associated with a first region of the transfer function than a second region of the transfer function; and an address module to calculate an index into the LUT based on image data. In one embodiment, the apparatus uses the LUT to process the image data.

    • Devices, systems, methods, and other embodiments associated with clipping instructions are described. In one embodiment, a method includes receiving a clipping instruction for clipping filtered values in a video image de-blocking operation. The clipping instruction references a video data value and a clipping value. The method includes decoding the clipping instruction. The method also includes retrieving the video data value and the clipping value. A video data magnitude of the video data value is determined. The method determines a clipping magnitude of the clipping value. A determination is made as to whether the video data magnitude exceeds the clipping magnitude. If the video data magnitude exceeds the clipping magnitude, the video data value is selectively clipped.

    • According to some embodiments, a Single-Instruction/Multiple-Data (SIMD) averaging instruction is used to process pixels of image data. The averaging instruction generates a set of four-pixel averages, where each average is generated from two pixels in a first source register and two pixels in a second source register. The first source register contains a plurality of pixels from a first row of pixels and the second source register contains a plurality of pixels from a second row. In one embodiment, the first and second rows are adjacent rows in an image and the averaging instruction is used, for example, to down-scale an image, perform color conversion, and the like. In another embodiment, the first and second rows are from different images and the averaging instruction is used, for example, in motion estimation for video encoding, in motion compensation for video decoding, and the like.
    • 根据一些实施例,使用单指令/多数据(SIMD)平均指令来处理图像数据的像素。 平均指令产生一组四像素平均值,其中每个平均值由第一源寄存器中的两个像素和第二源寄存器中的两个像素生成。 第一源寄存器包含来自第一行像素的多个像素,并且第二源寄存器包含来自第二行的多个像素。 在一个实施例中,第一行和第二行是图像中的相邻行,并且使用平均指令来例如缩小图像,执行颜色转换等。 在另一个实施例中,第一行和第二行来自不同的图像,并且平均指令用于例如用于视频编码的运动估计,用于视频解码的运动补偿等。
