This kernel is used to compute a dynamic Hanning Window for every transducer. So, this kernel is used to calculate the apodization for the reception.

  • Template params:
    • T: type of the operation;
    • LEN_OUT: number of outputdata per invoking;
    • LEN_IN_F: number of inputdata per invoking;
    • LEN_IN_D: number of inputdata per invoking;
    • VECDIM: dimension of the SIMD to be performed. Addressed in the Xilinx UG1076, it depends on the type chosen;
    • APODI_PRE_LEN32b_PARA: number of RTP data per invoking;
  • Kernel Inputs:
    • para_const: kernel_apodization_main self-used structural parameters include iter_line and iter_element and so on. It’s definition could be seen in L1/include/kernel_apodization_main.hpp;
    • p_focal_in: Result of Focusing;
    • p_invD_in: The result of kernel_apodization_preprocess output;
  • Kernel Outputs:
    • p_apodization_out: A vector which represents our Hanning Window for the reference point chosen;
