CupvaSamplerTiles

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

struct CupvaSamplerTiles

Configure an array of tile coordinates for sampling 2D patches with bilinear interpolation.

This structure should be used to pass parameters to one of the cupvaSamplerInit() overloads. Where a field is specified as optional, a default value may be used by leaving the relevant entry zero/default initialized.

Public Members

void const *data

Pointer to input tile data array. Each element should be unsigned 32bit, element layout determined by value provided for type.

CupvaSamplerTileType type

Format of tile data. Optional, defaults to SAMPLER_TILE_TRANS_ONLY (i.e. x/y coords, no scale)

uint8_t width

Width of each tile in pixels

uint8_t height

Height of each tile in pixels

uint16_t count

Number of tiles in the array

uint8_t fractionalBits

Number of fractional bits in the tile data. Optional, defaults to zero.

int32_t offsetX

Constant positive or negative X offset which is applied to all tiles-> Optional, defaults to zero.

int32_t offsetY

Constant positive or negative Y offset which is applied to all tiles-> Optional, defaults to zero.

CupvaSamplerTileTraversalMode tileTraversalMode

Order in which tiles are traversed. Optional, defaults to SAMPLER_TRAVERSAL_STANDARD.
