Abstract: Provided are a filter unit and a filter array, and the filter unit includes: a control module (10) configured to analyze configuration information of the filter unit, and control selection of internal functions and flow direction of data in the filter unit; a filtering module (20) connected to the control module (10), and configured to perform an operation on internal data of the filter unit and perform a sampling rate conversion function under control of the control module (10); and an output selection module (30) connected to the control module (10) and the filtering module (20), and configured to perform a selection function on output data of the filtering module (20) under control of the control module.

Abstract: The present application provides a data acquisition method, a data acquisition apparatus, a data acquisition device and a storage medium. The data acquisition method includes: obtaining a first storage flag for indicating a flag bit at which first data starts to be acquired and stored; when a first data acquisition clock is asynchronous with a second data acquisition clock, obtaining a second storage flag being a storage flag bit corresponding to the first storage flag after the first storage flag crosses from the first data acquisition cock to the second data acquisition clock, according to the first data acquisition clock and the second data acquisition clock; and performing anti-jitter processing on the second storage flag to obtain a third storage flag, and acquiring second data according to the third storage flag, a delay between the first data and the second data acquired each time is kept unchanged.

Abstract: Disclosed are a multimode decoder method and device. The method includes: interleaving pre-stored to-be-decoded data to obtain an interleaving address; and based on the interleaving address, using a Radix-4 algorithm architecture, multiplexing a set of MAP decoding units under different standards, and in a parallel processing method, performing MAP iterative decoding processing on the to-be-decoded data according to standard types.
