    摘要： Techniques for efficiently performing full and scaled transforms on data received via full and scaled interfaces, respectively, are described. A full transform is a transform that implements the complete mathematical description of the transform. A full transform operates on or provides full transform coefficients. A scaled transform is a transform that operates on or provides scaled transform coefficients, which are scaled versions of the full transform coefficients. The scaled transform may have lower computational complexity whereas the full transform may be simpler to use by applications. The full and scaled transforms may be for a 2D IDCT, which may be implemented in a separable manner with 1D IDCTs. The full and scaled transforms may also be for a 2D DCT, which may be implemented in a separable manner with ID DCTs. The 1D IDCTs and 1D DCTs may be implemented in a computationally efficient manner.

    摘要： Techniques for efficiently performing computation for signal and data processing are described. For multiplication-free processing, a series of intermediate values is generated based on an input value for data to be processed. At least one intermediate value in the series is generated based on at least one other intermediate value in the series. One intermediate value in the series is provided as an output value for a multiplication of the input value with a constant value. The constant value may be an integer constant, a rational constant, or an irrational constant. An irrational constant may be approximated with a rational dyadic constant having an integer numerator and a denominator that is a power of twos. The multiplication-free processing may be used for various transforms (e.g., DCT and IDCT), filters, and other types of signal and data processing.
