gpuSimulateCudaBasebandBeamformer

class gpuSimulateCudaBasebandBeamformer : public kotekan::Stage

Stage for faking CUDA baseband beamforming.

Buffers

• voltage_in_buf Voltages

  • Format: Int4+4

  • Metadata: chimeMetadata or oneHotMetadata

• phase_in_buf Beamformer phases

  • Format: Int8

  • Metadata: chimeMetadata or oneHotMetadata

• shift_in_buf Number of bits to shift result

  • Format: Int32

• beams_out_buf Output buffer for formed beams

  • Format: Int4+4

  • Metadata: Copied from voltage_in_buf

Param num_elements:

Int. Number of dishes x polarizations.

Param num_local_freq:

Int. Number of frequencies in each frame.

Param samples_per_data_set:

Int. Number of time samples per frame.

Param num_beams:

Int. Number of beams being formed.

Param zero_output:

Bool. Zero out the array before filling it? Useful when doing one-hot sparse outputs.
