The template parameters TP_POINT_SIZE and TP_NUM_FRAMES determine the number of samples of the input/output buffers. When TP_NUM_FRAMES is set to 1, the input/output buffer size will be equal to FRAME_SIZE (TP_POINT_SIZE zero-padded for alignment). However, when the number of frames is greater than one, the input/output buffer of data will contain TP_NUM_FRAMES batches of FRAME_SIZE input data.
