An Implementation Method of K-tap FIR Filter Using Vector Processor (Method for Emboding K-tap FIR Filter Using Vector Processor)

摘要

The present invention relates to a method of implementing a k-tap FIR filter using a vector processor, and more particularly, to a method and an apparatus for processing a k tap FIR filter using a vector processor, in which a vector processor is used to multiply shifted k tap vector elements of a first vector register and coefficients of a corresponding second vector register A multiplication step; An addition step of adding all k tap vector elements multiplied in the multiplication step; And a storing step of storing the added value in a third vector register.;Therefore, the vector processor of the FIR filter of the present invention has the effect that the calculation speed is improved by reducing the output calculation by multiplying the tap number and the output by the number of data, which is the vector element, compared to using the existing Scalar DSP.
