Implementation of k-tap 11R filter using vector processor

摘要

The present invention relates to a method of implementing a k-tap IIR filter using a vector processor, and more particularly, to a method of generating a k-tap IIR filter using a vector processor and a multiplication step of multiplying a vector element of a first vector register by a multiplication coefficient of a second vector register using a vector processor. A storing step of storing the value multiplied by the multiplication in a third vector register; An addition step of adding all the vector elements stored in the third vector register; And an input step of inputting a result value added in the adding step into a predetermined vector element of a first vector register of a next tap.;Therefore, the horizontal vectorization vector processor of the IIR filter according to the present invention has the effect of improving the calculation speed by reducing the output calculation by multiplying the number of taps and output by the number of vector elements, as compared with the case of using the existing Scalar DSP.
