    摘要: In one embodiment, a DSP structure includes four main sections: DEQ, IDCT for row, IDCT for column, and motion compensation. The data input sequence is organized in such a way to facilitate the data loading into hardware structures for row IDCT and column IDCT. Two types of decoding flows are enabled by the DSP structure: H.264 decoding flows (e.g., dequantization, inverse discrete Hadamard transform, intra prediction, and motion decompensation), and non-H.264 decoding flows (e.g., dequantization, row inverse discrete cosine transformation, column inverse discrete cosine transformation, and motion decompensation). The non-H.264 decoding flow can be used for standards such as MPEG1/2/4, H.263, Microsoft WMV9, and Sony Digital Video.

    摘要: A shared pipeline architecture is provided for H.264 motion vector prediction and residual decoding, and intra prediction for CABAC and CALVC entropy in Main Profile and High Profile for standard and high definition applications. All motion vector predictions and residual decoding of I-type, P-type, and B-type pictures are completed through the shared pipeline. The architecture enables better performance and uses less memory than conventional architectures. The architecture can be completely implemented in hardware as a system-on-chip or chip set using, for example, field programmable gate array (FPGA) technology or application specific integrated circuitry (ASIC) or other custom-built logic.

    摘要: A design technique is disclosed that allows video processing hardware designers to effectively employ the requirements of a video processing standard (e.g., H.264 specification or other such standard) during the hardware architecture design phase of the design process. The technique eliminates or otherwise reduces costly multiple passes through the resource intensive implementation and verification portions of the design process, and allows designers to make changes to the hardware architecture design, thereby ensuring verification at the implementation phase.

    摘要: A video compression scheme enables the user to select one of many video compression formats, including the widely-used standard video formats such as MPEG-1, MPEG-2, MPEG-4 and H.263. In one embodiment, the scheme is implemented as a hardware-software combination, with the hardware portion, preferably implemented as an ASIC chip, performing the core compression and the software portion dealing with the detailed formatting. In another embodiment, a 32-bit aligned transitional data format is used.

    摘要: A noise filter for a video processing system includes a block selector, a cost calculator, a cost table, a cost comparator, and a coefficient filter. The block selector is coupled to receive data from the quantization unit and selects blocks for additional filtering. The selected blocks are provided to the cost calculator determines a cost for each of the coefficients in the block using the cost table and the costs are summed. The cost comparator compares the total to a threshold, and filters the coefficients using the coefficient filter if the total is greater a preset threshold. The noise filter to the VLC unit then outputs the filter data.
