The invention provides an extensible QR decomposition method based on a pipeline working mode. A layered and cascaded structure is adopted, wherein pipeline operation is realized among layers; two lines of matrix data of each layer are subject to Givens rotation; the Givens rotation is conducted by using a coordinate rotation digital computer (CORDIC) algorithm and realized by using operations of addition and displacement; the layer number is determined by the line number or the row number of matrices; a whole QR decomposition module consists of a controller and a data processing module; a line rotation module is arranged on each layer of the data processing module; output ports of upper layers of line rotation modules are connected with input ports of lower layers of line rotation modules; the matrix data to be composed are input from an input port of the first layer of line rotation module, and sequentially flow through all the line rotation modules; and all the line rotation modules work in parallel. The scalable QR decomposition method has the advantages that hardware resources are saved; and as the iterative process of the CORDIC algorithm is split at the inner part of each layer of the data processing module, a pipeline structure is formed, the rotation operation of multiple vector groups is processed in a time sharing manner, the throughput rate is increased, and the extension is flexible.

The invention discloses an elastic filament brush and a matched electric slip ring. The elastic filament brush comprises an electric brush clip and an electric brush clip cover, which are buckled together. A metal elastic filament is clamped between the electric brush clip and the electric brush clip cover. An inner end of the elastic filament brush is provided with at least one metal elastic filament which is led out, and an outer end of the elastic filament brush is provided with at least one electric brush perforation which is used for the passing of a supporting bar. The electric slip ring matched with the elastic filament brush is formed by the alternate stacking of copper rings and copper ring spacers. The upper surface of each copper ring spacer is provided with an upper annular convex edge for the positioning of the corresponding copper ring, and the lower surface of each copper ring spacer is provided with a lower annular convex edge for the positioning of the corresponding copper ring. According to the invention, the elastic filament brush and the matched electric slip ring are simple in structure, and are resistant to wear. Moreover, the number of input / output conductors of a collector ring formed by the elastic filament brush and the matched electric slip ring can be increased flexibly, thereby meeting different needs.
