摘要： An MPEG-II audio decoder with a synthesis subband filter includes a fast IMDCT (Inverse Modified Discrete Cosine Transform) module and an IPQMF (Inverse Pseudo Quadrature Mirror Filter) module. The fast IMDCT module involves a butterfly stage of input subband samples which requires only about ¼ the amount of multiplier-accumulate computation of the ISO suggested method. The IPQMF module involves an efficient memory configuration which requires only half size of the standard synthesis subband filter bank.

摘要： The invention describes a simple and efficient codeword degrouping algorithm which can be applied in an MPEG audio decoder, in which a codeword is degrouped into three samples. According to the proposed algorithm, the division and modulo computations applied in the original degrouping method can be fully substituted into the addition and subtraction computations by using the mode selection and iterative decompositions, and thus largely reduces the overhead and complexity for the decoder. Also, an efficient architecture for the proposed algorithm includes one special adder, two subtractors, and two adders. The architecture generates the quotient and remainder simultaneously with fix-rate throughput.

摘要： An architecture for performing the two-dimensional discrete wavelet transform includes a transform module including a first stage and a second stage for decomposing an input image into four bands, and among the four bands, the band having the low frequency in both horizontal and vertical direction serves as the input image for next level decomposition operation; a multiplexer for selecting the band having the low frequency in both horizontal and vertical direction as the input image to feed into the transform module; and an optional memory module for storing the band having the lowest frequency in both horizontal and vertical direction. The polyphse decomposition technique is employed to the decimation filters of the first stage for segmenting the coefficients of the decimation filters of the first stage into an odd-numbered part and an even-numbered part, and the coefficient folding technique is employed to the decimation filters of the second stage such that every two coefficients of the decimation filters of the second stage share one set of a multiplier, an adder, and a register.

摘要： We discloses an efficient method for compressing a color image, visual block pattern truncation coding (VBPTC), in which the conventional block truncation coding (BTC) serves to encode an original image. This method defines the edge block according to human visual perception. If the difference between the two quantized values of BTC in a block is larger than a threshold which is defined by visual characteristics, the block will be identified as an edge block. In an edge block, the bitmap is adapted to compute block gradient orientation and to match the block pattern.
