The invention discloses a configurable data recombining network unit comprising a logarithm circulating shift register unit and a data distribution unit, wherein data output ports of the logarithm circulating shift register unit are correspondingly connected with data input ports of the data distribution unit. The data distribution unit comprises a first data selection unit, a second data selection unit and a control unit, wherein the first data selection unit comprises n selectors for selecting one datum from multiple data, the second data selection unit comprises n data-alternative selectors. The control unit is used for producing control and input signals of the data-alternative selectors of the second data selection unit. The configurable data recombining network unit can carry out circulating shift operation on a group of data with variable number in the efficient data, and the configurable data recombining network unit can preferably meet the requirements of the modern communication systems to the signal processing.
Description
technical field [0001] The present invention relates to the field of electronic technology, in particular to the field of data exchange technology, in particular to a configurable data reorganization network unit for cyclically shifting a group of data with variable valid data. Background technique [0002] The data reorganization network unit is an important structural unit used in the communication system to sort a set of data and output it to the subsequent processing unit for processing. In communication systems such as WIMAX and DVB-S2, the essence of sorting a set of data is to cyclically shift the set of data. In the prior art, a group of data is circularly shifted using a logarithmic circular shift register unit, and a logarithmic circular shift register unit with 8 inputs and 8 outputs has the following figure 1 and figure 2 structure shown. The structure is composed of a first data selection unit 110 , a second data selection unit 120 and a third data selection...
