Abstract

The embodiment of the invention discloses a data processing system and method which are applied in the technical field of data processing. In the data processing system of the embodiment in the invention, a first conversion unit utilizes multiple remainder groups which are mutually prime numbers to convert the input data represented by binary weight values to L-path conversion data represented bythe residue number system; a computing unit performs Fourier operation on the L-path conversion data independently, a second conversion unit converts the calculated data to the output data represented by binary weight values again; and a data processing unit is used to perform data processing. In the system of the embodiment in the invention, the Fourier operation of each path of conversion data is independent; and the processed bits of the data represented by the residue number system are fewer, thus the calculated path is shortened relatively, the data processing time is reduced and the working efficiency of the system can be increased.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data processing method and system. Background technique [0002] Existing data processing, such as channel estimation, signal analysis, and signal comparison in the communication field, should be widely used in Fourier analysis, and the corresponding processing of the data after Fourier analysis will make channel estimation, signal analysis, etc. The process is simplified. Among them, Fourier analysis can be realized by fast Fourier transform (Fast Fourier Transform, FFT) operation processing unit. FFT is a fast algorithm of discrete Fourier transform (DFT). Its appearance has greatly promoted the development of data processing systems. develop. The FFT operation processing unit in the existing data processing system can be realized by various algorithms such as radix-2, radix-4, and mixed-radix algorithms. [0003] With the increasing complexity of modern communicat...
