摘要： An ultrasonic system employs a path through a fluid to determine fluid density by a differential reflection coefficient measurement of fluid impedance Z and a fluid sound speed c. Preferred configurations use clamp-on (external) transducers and combine ultrasonic measurements of flow velocity V over one or more paths, to obtain the mass flow rate. Z is determined by comparing reflections from a reference target, which may be totally reflective, with reflections from a sensor target having an effectively lower Z, which may be close to that of the fluid. Both targets are preferably located to be cleaned by the natural flow of the fluid. The low-Z target is interrogated at least once. Vee blocks provide a compact combination of reference and sensor targets that can be integrated with a velocity-sensing flowcell. Folded-path flow cells compactly measure V alone or in combination with density. The principal surface may be aligned parallel to the free stream direction and located to yield a flow value substantially equal to the area averaged flow, and the system may further correct for variations in the vicinity of the reflector.

摘要： A method for performing fast multiplication in a microprocessor is disclosed. The method comprises detecting multiplication operations that have a floating point operand and an integer operand, wherein the integer operand is an integer power of two. Once detected, a multiplication operation meeting these criteria may be executed by using an integer adder to sum the integer power and the floating point operand's exponent to from a product exponent. The bias of the integer operand's exponent may also be subtracted. A product mantissa is simply copied from the floating point operand's mantissa. The floating point operand's sign bit may be inverted to form the product's sign bit if the integer operand is negative. Advantageously, the product is generated using integer addition which is faster than floating point multiplication. The method may be implemented in hardware or software.

摘要： A video system examines the transform domain content of various spatially related blocks in a compressed video bitstream to determine whether predetermined types of similarities exist between multiple blocks. When certain selected similarities are found, the video system spatially combines the blocks in a predetermined manner. In some embodiments, DCT coefficients of a plurality of blocks are averaged to form one averaged block and the averaged block is inverse discrete cosine transformed. The averaged and IDCT transformed block is written to the display at the position of each of the averaged blocks. In some embodiments, a representative block of a plurality of DCT coefficient blocks is selected and inverse discrete cosine transformed. The selected and IDCT transformed block is written to the display at the position of each of the plurality of blocks.

摘要： An video decoder system, such as for use with MPEG video compression, uses a previous B-frame as an additional prediction source for the current B-frame. In one embodiment, a given block within a current B-frame "N" reuses IDCT result terms from the previous B-frame "N-1" if they are determined to be "similar enough" to the anticipated IDCT result terms which would otherwise need to be computed. For a given block, each of the "M" lowest-frequency DCT coefficients for B-frame "N" and B-frame "N-1" are respectively compared: if they differ by less than a similarity threshold value, then the IDCT result terms from the previous B-frame "N-1" are reused without further computation. The similarity threshold may be adaptively adjusted to reduce the computational burden of video decompression, while affording a gradual degradation of picture quality, rather than wholesale skipping of entire frames.

摘要翻译： 诸如用于MPEG视频压缩的视频解码器系统使用先前的B帧作为当前B帧的附加预测源。 在一个实施例中，当前的B帧“N”中的给定块重新使用来自先前B帧“N-1”的IDCT结果项，如果它们被确定为与预期的IDCT结果项“足够相似” 需要计算。 对于给定的块，分别比较用于B帧“N”和B帧“N-1”的“M”个最低频率DCT系数中的每一个，如果它们相差小于相似性阈值，则IDCT 来自前一个B帧“N-1”的结果项被重新使用，无需进一步的计算。 可以自适应地调整相似性阈值，以减少视频解压缩的计算负担，同时提供图像质量的逐渐劣化，而不是批量跳过整个帧。
