摘要： A volume rendering integrated circuit includes a plurality of interconnected pipelines having stages operating in parallel. The stages of the pipelines are interconnected in a ring, with data being passed in only one direction around the ring. The volume integrated circuit also includes a render controller for controlling the flow of volume data to and from the pipelines and for controlling rendering operations of the pipelines. The integrated circuit may further include interfaces for coupling the integrated circuit to various storage devices and to a host computer.

摘要： A plurality of identical rendering pipelines are connected in parallel to read an array of voxels and to write an array of pixels. Each pipeline processes one voxel in one processing cycle of the pipelines. Each pipeline includes a plurality of serially connected different stages. The stages can include interpolation, classification, gradient estimation, illumination, and compositing stages. Interfaces connect identical stages in adjacent pipelines as one-way rings to communicate information associated with spatially adjacent voxels, and delay buffers connected parallel to particular stages communicate information associated with temporally adjacent voxels.

摘要： A method compresses synthetic aperture radar (SAR) data by sampling the SAR data into blocks and transforming each block to a corresponding block of transform coefficients. Each block of transform coefficient is quantized according to a quantization parameter to obtain a corresponding block of quantized transform coefficients, which are demultiplexed into sets of blocks of quantized transform coefficients. The quantized transform coefficients in the blocks in each set are arithmetically encoding in parallel according to a probability model to produce an intermediate bitstream for each set of blocks. The encoding of the quantized transform coefficients of one block is independent of the quantized transform coefficients of a successive block. The intermediate of bitstreams are then multiplexed to a compressed bitstream, which can be transmitted, or stored, for subsequent decoding to construct an SAR image.
摘要翻译：一种方法通过将SAR数据采样到块中并将每个块变换成相应的变换系数块来压缩合成孔径雷达（SAR）数据。每个变换系数块根据量化参数进行量化，以获得量化变换系数的相应块，其被解复用为量化变换系数块集合。每组中的块中的量化变换系数根据概率模型并行地进行算术编码，以产生每组块的中间比特流。一个块的量化变换系数的编码与连续块的量化变换系数无关。然后将比特流的中间复用到可以被传输或存储的压缩比特流，以便后续解码以构建SAR图像。
