摘要： A circuit for squaring a binary number X of n bits, x.sub.0 to x.sub.n-1, includes pre-processing circuits to form a group of all the products x.sub.i y.sub.j of the bits of number X, where i and j vary between 0 and n-1 such that i.ltoreq.j. The outputs of the pre-processing circuits provide words such that each word is formed by a succession, as complete as possible, of products selected among the products remaining from the group of products after forming the preceding word, each product x.sub.i y.sub.j of this succession being affected with a weight i+j+1 of the word if i is different from j, or with a weight 2i if i=j. Adders are connected to sum the words as the square of the number X.

摘要： A Reed-Solomon type error correction device carries out correction passes, and includes a first memory containing DVD type data, as well as CD type data after a first correction pass, for deinterleaving of the CD type data before a second correction pass. Additionally, a second memory of smaller capacity than the first memory, is provided for containing CD type data before correction, as well as deinterleaved CD type data. The invention concerns the error correction device and an optical disk reader containing such a device.

摘要： A compact and fast coder-decoder of the Reed-Solomon type and a reader, which comprises such a coder-decoder. The present invention provides a coder-decoder that includes specific registers that are divided into elementary cells set in series and comprising means of multiplexing and of calculation such that during a cycle of a clock signal the data of two of the registers are shifted from one cell and a calculation operation is carried out for one of the data and it is subsequently possible to exchange simultaneously the data between the two registers.

摘要： A method of processing data in matrix arrays in a motion estimation system is characterized in that each array (803, 804) performing a calculation of distortion (Err) for a block of pixels (1, 2) of a current image, at least two arrays (803, 804) being arranged in series performing the calculations for at least two adjacent blocks (1, 2) of the said current image, the reference window corresponding to the entirety of these blocks being introduced in bands of pixels into the first of the said arrays (803) and propagating from array to array in the said series of arrays, the allocation of the blocks (1, 2) to the arrays and the direction of introduction of the band into the arrays being such that the last part (c, respectively A) of the band introduced into the array corresponds to a part of the window of the block (2, respectively 1) allocated to the first of the arrays (803).
摘要翻译：一种在运动估计系统中处理矩阵阵列中的数据的方法的特征在于，每个阵列（803,804）对当前图像的像素块（1,2）执行失真（Err）的计算，至少两个阵列（803,804）串行布置地执行对所述当前图像的至少两个相邻块（1,2）的计算，对应于这些块的整体的参考窗口被引入到像素的第一个所述阵列（803）并且在所述一系列阵列中从阵列传播到阵列，块（1,2）到阵列的分配和将阵列引入阵列的方向使得最后部分引入阵列的频带的A分别对应于分配给第一阵列（803）的块（2，分别为1）的一部分窗口。
