The Vitis™ DSP Library (DSPLib) is a library of commonly used DSP functions optimized for AI Engines. To facilitate the use of these functions in a design, Vitis™ Model Composer provides different DSPlib functions as blocks within the Xilinx Toolbox/AI Engine/DSP library. You can conveniently drag and drop one of these blocks into your model from the Simulink Library browser and configure the block.
