Digital signal processing system

摘要

A digital signal processing system for receiving from a Fourier Transform processor a first multiplicity of data points which together represent a Fourier Transform and processing the first multiplicity of data points to generate a second multiplicity of data points which together represent one or more other Fourier Transforms, comprises: a processing means for processing the first multiplicity of data points to generate the second multiplicity of data points by processing a plurality of pairs of data points of the first multiplicity of data points, each pair of data points comprising first and second data points that are to be processed together at the processing means. The system further comprises a circuit for connecting the Fourier Transform processor and the processing means to route the first multiplicity of data points from the Fourier Transform processor to the processing means, in use the circuit being controlled so that the first and second data points of any given pair of the plurality of pairs of data points are input to the processing means substantially simultaneously and with at least one of them having been routed from the Fourier Transform processor to the processing means without being stored in memory. The system provides for reduced latency and memory requirements compared to known systems.
