RDF_CIRCULAR_COLUMNMAJOR#

Defined in src/device/vpu_runtime/include/cupva_device/device_core.h

RDF_CIRCULAR_COLUMNMAJOR(type, tw, th, haloX, haloY, ...)#

Calculate the minimum buffer length (in pixels) required to support a circular layout for RasterDataFlow in column-major traversal.

This macro behaves similarly to RDF_CIRCULAR, however it assumes that the buffer needs to only support column-major traversal. In some cases, this may lead to reduced VMEM usage compared to supporting both row-major and column-major.

Parameters:

  • type – The pixel data type

  • tw – Tile width in pixel

  • th – Tile height in pixel

  • haloX – Horizontal halo in pixel

  • haloY – vertical halo in pixel

  • ... – Optional argument, the transposition mode. Defaults to TRANS_MODE_NONE.
