CUPVA_DOUBLE_BUFFER_LENGTH

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

CUPVA_DOUBLE_BUFFER_LENGTH(tw, th, ...)

Calculate the VMEM buffer length (in pixel) of double layout according to different configurations.

The buffer length will be 64-pixel aligned.

Deprecated:

This macro is deprecated due to memory usage increases while the BPP > 1, and replaced with RDF_DOUBLE.

Parameters:

• tw – Tile width in pixel (arena width, if RasterDataFlow::tileArena() API will be used)

• th – Tile height in pixel (arena height, if RasterDataFlow::tileArena() API will be used)

• ... – Optional arguments, specified in the following order:

  • haloX gives horizontal halo in pixel, defaults to 0

  • haloY gives vertical halo in pixel, defaults to 0

  • type gives the pixel data type, ignored if transposition mode is TRANS_MODE_NONE

  • mode gives the transposition mode, defaults to TRANS_MODE_NONE
