In this step, identify the required functions available in the DSP library. This MATLAB model design requires a symmetrical FIR filter and FFT.
DSPLib contains several variants of FIR filters. The library categorizes FIR filters into classes and places them in a distinct namespace
scope:xf::dsp::aie::firto prevent name collision in the global scope.DSPLib contains one FFT/iFFT solution: a single-channel, decimation-in-time (DIT) implementation. The solution has a configurable point size, data type, forward/reverse direction, scaling (as a shift), cascade length, static/dynamic point size, window size, interface API (stream/window), and parallelism factor.
